(ANNONACEAE) IN AUSTRALIA L.W. Jessup Queensland Herbarium, Meiers Road, Indooroopilly, Qld 4068 Summary Three new ae and one new variety in Pseuduvaria Mig. from north-eastern Queensland are described. They are P. hylandti, P. villosa, P. mulgraveana vat. mulgraveana and P. mulgraveana var. glabrescens. The palaeotropical genus Pseuduvaria currently with about 35 species was first proposed by Miquel (1858) but remained in obscurity following inclusion in Mitrephora by Bentham and Hooker (1862) until Merrill (1915) proposed its recognition and made several new combinations. Sinclair (1955, 1956) and others accepted Merrill’s viewpoint and published additional species. In Australia, Mueller (1887) followed the Bentham and Hooker concept when describing Mitrephora froggattii F.Muell. from Queensland. This species was transferred to Pseuduvaria by Jessup (1986). Three new species and one new variety, all from north- eastern Queensland, are here described. Living plants of all species were studied. Floral and fruit measurements provided were taken from material preserved in spirit. PSEUDUVARIA Pseuduvaria Miquel, Fl. Ind. Bat. 1(2): 32 (1858). Type: Pseuduvaria reticulata (Blume) Miquel based on Uvaria reticulata Blume. Dioecious shrubs or trees. Leaves with slightly curved, + parallel secondary veins; tertiary venation scalariform-reticulate. Flowers cauline, ramal, axillary or sometimes terminal, solitary or several, sometimes many in fascicles. Pedicels slender, slightly tapering, thickened towards the flower; bracts 2, basal and submedial or suprabasal; articulation between the bracts. Calyx lobes 3, valvate. Petals 6, in 2 series, valvate, outer 3 larger than calyx lobes, spreading or reflexed; inner 3 larger than outer, each with a trullate, broadly thombic or obtrullate blade and a narrow claw; blade margins coherent forming a trifenestrate dome-like cap; blades with 2 raised glands on inner surface; claw shorter than blade. Torus rounded, pilose. Male flowers: stamens ca 60, truncate-cuneate: connective flat-topped, concealing anthers. Female flowers: staminodes usually 6-18. Ovaries numerous, the peripheral ones incurved; ovules few, superposed; stigma sessile, depressed capitate with an adaxial radial slit. Ripe monocarps sessile in Australian species.

Distribution and Habitat: This variety is found from just north of Kuranda to Little Mulgrave River, in northern Queensland and occurs on uplands and foothills extending in places down to lower footslopes in notophyll vine forest mostly on soils derived from granite and metamorphic rocks. Affinities: P. mulgraveana appears most closely related to P. villosa and both varieties differ from it by obovate to depressed obovate and shorter outer petals and the abaxial leaf surfaces being hirtellous, glabrescent. Etymology: The valleys of the Mulgrave and Little Mulgrave River form a significant and central part of the species’ distribution. The Francis collection from Freshwater Creek was annotated by C.T.White sometime after 1930 with the following note: ‘should say M. froggattii after examination of the types C.T.W.’ This incorrect determination led to the subsequent misapplication of the name Mitrephora froggattii to this species by Queensland botanists. 4, Pseuduvaria villosa Jessup, sp. nov.

Distribution and Habitat: This species is found from the North Johnstone River to Liverpool Creek, in northern Queensland and occurs in the understorey of complex mesophyll vine forest on basalt derived soil or alluvial terraces formed substantially from basaltic parent material . Affinities: P.viliosa appears most closely related to P.mulgraveana and differs from it by the broadly ovate, acute or acuminate outer petals and the abaxial leaf surfaces being conspicuously villous. Etymology: The specific epithet refers to the long soft hairs on the leaves and branchlets. Acknowledgements I am grateful for the assistance of Garry and Nada Sankowsky in collecting specimens.

G.DON) PEDLEY (LEGUMINOSAE: MIMOSOIDEAE) AND RELATED SPECIES IN NORTHERN AUSTRALIA L. Pediey Queensland Herbarium, Meters Road, Indooroopilly, Qld 4068 Summary New combinations are Racosperma deltoideum, R. adenogonium, R. froggattii, R. stipulosum and R. sublanatum, based on Acacia deltoidea Cunn, ex G.Don, A. deltoidea var. pungens Benth., A. froggattii Maiden, A. stipulosa F.Muell. and 4. sublanata Benth., respectively. All species are described. Notes on their geographic ranges and habitats in the extreme north of Western Australia and in the Northern Territory and a key to their identification are given. A. deltoidea is lectotypified. If the treatment of Acacia Miller sens. lat. proposed by Pedley (1986) is accepted then species currently referred to Acacia subg. Phyllodineae Seringe will have to be transferred to Racosperma Martius. Though it would be desirable to make the transfers en masse, practical considerations dictate a piecemeal approach. As the results of revisionary studies are published individual authors will have to decide whether to include Racosperma in Acacia or to treat 1t as a distinct genus. Having argued for the latter course, I therefore make new combinations under Racosperma. Names are available for = the described taxa under Acacia, though in the case of one species only at varietal rank. The species treated here constitute, with Racosperma pravifolium (F.Muell.) Pedley and R. amblygonum (Cunn. ex Benth.) Pedley, the Triangulares group of Acacia section Plurinerves in the classification of Pedley (1978). They have usually setaceous stipules and plurinerved broadly falcate-ovate or triangular phyllodes. The flowers are in globular heads, rarely spikes, on peduncles solitary in the axils. Maslin (1978) dealt with the 4- merous members of the Triangulares group of Acacia section Phyllodineae and sum- marised the various ways Bentham had treated Triangulares. The type species of Bentham’s original Acacia subseries Triangulares is the uninerved Acacia biflora R.Br. (syn. A. triangularis Benth.) (Pedley 1980). If the plurinerved species are considered to constitute a subseries different from the subseries 7riangulares with uninerved species, then it has no legitimate name. No attempt will be made to name or typify it here. A detailed infrageneric classification of Racosperma would be of considerable value and interest but requires an appraisal of approximately 750 species. Little can be achieved in taking a group of only five of these in tsolation. Relationships of R. deltoideum and its immediate allies are not clear. The lobing of the calyxes and the striate corollas of some species, and the stipules of some suggest an affinity with species of Racosperma section Lycopodiifolia. The calyxes of R. aden- ogonium and R. deltoideum are similar, for example, to those of R. lycopodiifolium (Cunn. ex Hook.) Pedley and Acacia adoxa Pedley (see Fig. 1d & g, Pedley 1972). The characters may be the result of convergent evolution rather than an indication of true affinities but, as the affinities of the Lycopodiifolia are not at all obvious, the possibility of a relationship should not be dismissed. Maiden (1920) when describing Acacia froggattii referred A. stipulosa to A. deltoidea and accepted A. /uehmannil. Bentham (1864) had identified some specimens of Robert Brown, allegedly collected in southern Australia, as A. sublanata, to which he referred A. pravifolia. Court (1972) pointed out that Brown’s specimens came from northern Australia and that A. sublanata and A. luehmannii were conspecific. Distributions of species are given using the numbers of the map sheets of the 1:250 000 Topographic Map Series R502 produced jointly by the Divison of National Mapping and the Royal Australian Survey Corps. 315 Key to Species 1.

Coast, Cunningham (K). Distribution: Western Australia in Gardner Botanical District, on shallow soil derived from limestone (1:250 000 map sheets: D51-12,16; D52-9,10; E51~3,4). Lectotypification of the name Acacia deltoidea is necessary. Don’s description of the species was probably based on a number of Cunningham’s collections at the British Museum (Natural History), including one now referred to Racosperma adenogonium. As the protologue could apply to either species the lectotype is chosen to ensure that the generally accepted application of the name Acacia deltoidea is unchanged.The Forrest specimen cited above, which originated from the National Herbarium of Victoria (MEL), was determined there as Acacia stipulosa. The determination was later confirmed by C.A.Gardner who annotated the PERTH sheet ‘Acacia stipulosa FvM/Agrees with the type’. This specimen or a duplicate may have been the source of the widespread belief that A. stipulosa and A. deltoidea were conspecific. Maiden (1920) placed A. stipulosa in the synonymy of A. deltoidea on the basis of the specimen ‘comm. Dr.F.Stoward’. Stoward who was botanist with the Department of Agriculture of Western Australia from 1911 to 1917 (Hall 1978) probably passed on to Maiden part of the specimen received from Melbourne. Gardner 996 & 1496 appear to constitute a single collection. They were collected at the same place on the same day. Their phyllodes (2 cm long) are about twice as m5 as those of other specimens but certainly should be referred to R. deltoideum. Kenneally 8365 and Fryxell & Craven 3893 have a conspicuous projecting gland similar to that of R. adenogonium, but the floral structure and indumentum suggest that they should be placed in R. deltoideum. Another collection, Fitzgerald 1421 (Edkins Range, Aug 1905 - see Fig. 1J & K) is more aberrant. Its phyllodes are small, though within the normal size range, with a somewhat projecting gland, and can scarcely be described as triangular. Because of its glandular hairs it is placed in R. deltoideum. Its flowers are too immature to be of value in identification. 2. Racosperma adenogonium Pedley, nom. et stat. nov.

Distribution: The extreme northern part of the Northern Territory on sandy soils, sometimes shallow, usually on sandstone but recorded also from coastal dunes (1:250 000 map sheets: D53-1,2,3,4,5,8). Bentham (1864) referred Acacia pravifolia to A. sublanata and recorded it as ‘South Coast, R.Brown’. Court (1972) clarified the matter after examining types and Brown material from northern Australia. A. pravifolia has straight hairs, smaller heads on shorter peduncles and obtuse broad-based bracteoles. In R. sublanatum there is considerable variation in the size of phyllodes from plant to plant but indumentum and floral characters show only a small range of variation, and there are no grounds for recognising infraspecific taxa. The occurrence of plants with flowers in spikes rather than in heads is an example of how closely allied Acacia section Plurinerves and A. section Juliflorae are. These two sections have been combined as Racosperma section Plurinervia (Pedley 1986). References BENTHAM, G. (1864). Acacia in Flora Australiensis Vol. 2, London: Reeve & Co. COURT, A.B. (1972).

Pedley, with which 2. paniculatum has been confused, are described. Flowers of R. fleckeri (Pedley) Pedley, are described for the first time. These are all members of the ‘Oligoneura group’ of Racosperma which is here defined. Other new species are R, meiosperrnum and R. polyadenium. All species are referred to Racosperma sect. Plurinervia. Species of Acacia Miller subg. Phyllodineae (DC.) Seringe (A. subg. Heterophyllum Vassal) should be referred to the genus Racosperma Martius (Pedley 1986). Only a small proportion of the formal transfer of names has been made. A checklist of Queensland species is included in this volume (Pedley 1987). Since publication of the revision of the Queensland species (Pedley 1978, 1980 as Acacia) several others have been described for the State (Pedley 1981, Pedley & Forster 1986). Five species from tropical Queensland are described here. All are referred to Racosperma sect. Plurinervia (Benth.) Pedley.

Typus: Sandy Tate River, Feb 1928, Brass 1745 (holo: BRI; iso: CANB,K,MO). Shrub to 3 m high, young branchlets angular, red-brown, resinous, sometimes with scattered hairs to 1 mm long, becoming grey and terete when old. Phyllodes Straight or slightly falcate, the lower margin + straight, the upper curved, covered with brown resin when young, losing it when older, 7-12.5 cm long, 2-3 cm wide, 3—5 times as long as wide, with many close parallel, non-anastomosing nerves, 3-5 more prominent than the rest; gland basal or almost so. Pulvinus 5-10 mm long. Stipules ovate, to 3 mm long when phyllodes first formed. Flowers in dense spikes 1.6-2 cm long, the rachis and peduncles with dense white hairs; peduncles 5 mm long, subtended by a striate concave bract to 3 mm long when young, arranged along an axillary axis, usually extremely short so that a group of 3-4 spikes is produced in each axil but occasionally the axis growing out into a leafy shoot with spikes well spaced along it. Flowers 5-merous. Calyx lobes narrowly oblong, slightly widened and thickened at the tip, free almost to the base, 1.5 mm long, villose with white hairs. Corolla lobes + free, 1.7 mm long, a few long hairs along the midline. Stamens 3-4 mm long. Ovary not seen (none present in flowers examined). Pods with up to 12 seeds, 8 cm long, 3 mm wide, obscurely longitudinally ribbed. Seeds 3.5 mm long, about twice as long as wide, longitudinally arranged; funicle creamy white, thickened and 2-3 times folded forming aril at base of seed; pleurogram fine, associated with pale area of seed coat; areole small with a narrow opening, about twice as long as wide.

Distribution: The species is confined to a small area about 40 km south-east of Chillagoe where 1t forms pure stands on shallow stony soils. Notes and Observations: Young plants are pubescent and long hairs persist on the branches and phyllodes of some mature plants. The resemblance to R. brassii may not indicate a close relationship.

Typus: Shaw Is., Lindeman Group, 6 Nov 1985, G.N. Batianoff 3354 & C. Dalliston (holo: BRI; ‘iso: K,MO,NSW). Shrub or small tree; branchlets slender, angular, at first very resinous. Phyllodes straight or slightly falcate, reddish brown and resinous when young, losing resin when old, somewhat acute with callus tip, 40-85 mm long, 2.8-5 mm wide, 12-20 times as long as wide, longitudinal parallel nerves not crowded (about 14 when phyllodes is wide), midnerve always conspicuous and two others sometimes so when phyllode is wide; gland small, basal, with 1-3 small glands along the margins, the lowest 12~25 mm from the base, the others at irregular intervals. Pulvinus ca 1 mm long. Stipules linear, about as long as the pulvinus, caducous. Flowers in somewhat open spikes, singly or in pairs in the upper axils; peduncles ca 6 mm long, resinous; rachis 12-20 mm long, resinous, elongating quickly following anthesis. Flowers 5-merous. Calyx wide cup-shaped, not closely investing the corolla, pale, membranous, glabrous, 0.6 mm long, lobed to about the middle the lobes lacking a midrib, somewhat thickened, apiculate, reflexed. Corolla ca 1.5 mm long, lobed to about the level of the calyx, petals reflexed. Stamens ca 2 mm long. Ovary densely pubescent. Pods with up to 8 seeds, 4.5 cm long, widest at the top, tapering to the base, rather woody, resinous, with margins thickened and obscurely longitudinally nerved faces, opening elastically from the top. Seeds not seen. Specimens examined. Queensland. NORTH KENNEDY DISTRICT: Palm Is., Henne (MEL 108106). SouUTH KENNEDY DISTRICT: Whitsunday Is., Henne (MEL 108105); Shaw Is., Lindeman Group, Jun 1985, Warrian (BRD, Nov 1985, Batianoff 3354 & Dalliston (BRI,K,MO,NSW). Distribution: The species is known from only three islands, one in the Lindeman Group, one 1n the Whitsunday Group and the other in the Palm Group some 350 km to the north-west. Such a distribution is unusual. None of the other narrowly distributed species of Racosperma of north-eastern Australian is confined to islands (see Maslin & Pedley 1982). Some of the islands of the central Queensland coast are visited by a lot of people each year and it 1s therefore remarkable that more than 100 years separated the collections of Henne and Warrian. Ecology: Ecological data are scanty. Warrian noted R. polyadenium as a small tree growing in heathland on a hillside overlooking the beach, while Batianoff and Dalliston reported it as a prostrate shrub 30 cm tall growing in wind-shorn scrub 3-4 m tall at an altitude of 42 m. Notes and Observations: Bentham (1864, p. 402) referred both of Henne’s specimens to Acacia drepanocarpa. The only other specimen cited by him was the type specimen which lacks flowers. Consequently he based his description of the flowers on the only flowering material available to him, which was Henne’s Palm Is. specimen. The descrip- tion 1s, however, not an accurate one. As already pointed out (Pedley 1978) the phyllodes of A. drepanocarpa illustrated by Mueller (1888) hardly belong to that species. They are a reasonable representation of the phyllodes of R. polyadenium. The ‘Oligoneura group’ The species keyed below belong to the complex of species related to R. excelsum (Benth.) Pedley (see Pedley 1978, p. 84). These are characterised by having phyllodes on short pulvinuses with prominent widely spaced longitudinal nerves with open, sometimes obscure, anastomosing nerves between them. The flower heads are in pairs or several pairs in the phyllode axils or, in one species, at nodes along leafless axes. One head matures before the other of the pair and the calyx lobes are ultimately free. Since one species of the complex, R. simsii (Benth.) Pedley is the lectotype of the name Acacia subseries Oligoneurae Benth. (Pedley 1980), the species are referred to here as the ‘Oligoneura group’. Bentham (1864) knew only four of the species included here, which he referred to two different subseries. LO. Ll. 323 A key to Australian species of the ‘Oligoneura group’ .

Distribution and Habitat: Known only from type locality in southern Queensland. Rare, growing in a small population of about 20 specimens in remnant scrubs. Affinities: A very distinctive species differing from all the other species of Alectryon known from Australia by the inflorescences clustered on old branches and the very variable and polymorphic leaves and leaflets especially in juvenile and adventitious shoots. Leaflets are also smaller, narrower and greater in number (usually 6-9 pairs) than in other species. Note: The mass of fruit on the branches was said to be so dense that it obscured about a 60 cm long portion of each branch. The wood is reported to be suitable for turning. Alectryon Gaertn. and Heterodendrum Desf. The finding of A. ramiflorus S.Reyn. has necessitated a reassessment of the variability and relationships of A/ectryon Gaertn. and Heterodendrum Desf. In the past they have been separated on their leaf character, pinnate in Alectryon and simple in Heterodendrum. Apart from this they are hardly distinguishable, having similar flowers and fruits, seeds and arils. For example, fruits of H. oleifolium Desf. resemble those of A, coriaceus (Benth.) Radlk. and A. repando-dentatus Radlk., while those of H. pubescens S.Reyn. are hardly distinguishable from those of A. subdentatus (F.Muell. ex Benth.) Radlk. H. pubescens closely resembles H. diversifolium F.Muell. in having entire or lobed leaves. Both can have leaves lobed or entire in the upper part and pinnate at the base. In this character they resemble A. subdentatus to such an extent that A. subdentatus has sometimes been thought to be an abnormal form or a hybrid with H. pubescens. Dr P.W.Leenhouts, Leiden, who is currently working on A/ectryon suggested (in litt.) the transfer of H. pubescens to Alectryon. However it is closely related to H. diversifolium and has the inflorescence of Heterodendrum. The small fruits and the shape and lobing of the leaves of A. ramiflorus resemble those of species of Heterodendrum. In this species leaflets of the same leaf can be entire, lobed or pinnate and on adventitous shoots the leaves are bipinnate with fine narrow leaflets, a condition not before seen in Australian Sapindaceae. Most species in this family develop simple leaves first (seedling stage), then lobed leaves (usually in juveniles), and finally pinnate leaves, for example, Atal/aya, Diploglottis and Harpullia. Species of some genera, for example, Atalaya and Dodonaea have either simple or pinnate leaves. Leaves of Atalaya variifolia F.Muell. ex Benth. can be simple, lobed or pinnate, sometimes on a single branch. Because of the variability of the leaves of Alectryon and Heteroden- drum, the occurrence of simple lobed and pinnate leaves in species of other genera of Sapindaceae, and the lack of other distinguishing characters, the two genera are combined here under the earlier name, A/lectryon. The distribution of Alectryon, including Heterodendrum is similar to some other genera such as Flindersia. Species of Alectrvon as formerly defined are mostly found in rainforests while those of Heterodendrum are found in drier areas, for example, in brigalow communities. H. oleifolium extends to the margins of deserts. 335 New combinations for species previously under Heterodendrum 1. Alectryon diversifolius (F.Muell.) S.Reyn., comb. nov.

Alectryon oleifolius (Desf.) S.Reyn. 1s a very variable and complex species with two other species reduced under it, namely H. macrocalyx Radlk. and H. microcalyx Radlk. These were previously treated as varieties ( Reynolds 1983,1985). Recent numerous additions to collections of this widespread species have necessitated the reassessment of this complex. It was found that differences between the three varieties were far greater than thought previously. Three quite distinct entities can now be segregated morphol- ogically and supported to a certain extent by ecological and distributional differences. The entities only connect with each other through a small proportion of specimens with somewhat intermediate characters. As these entities are not specifically distinct, as Radikofer (1879) had thought, and there 1s also a slight overlap in ecology and distribution, the varieties are here raised to subspecific rank. Necessary new combinations are made and the key in Reynolds 1983, p.483 is amended as indicated below. Some variation does occur in the subspecies and further collections may prove them to be distinct varieties but varietal status 1s not warranted at the present time. The epithets ‘macrocalyx’ and ‘microcalyx’ have been discounted in the choice of subspecific epithets as the size of the calyx varies in the same subspecies. Indumentum, leaf and inflorescence characters and the length of pedicels are used to separate the subspecies. 1.

Common name: Boonaree, Australian Rosewood, Western Rosewood. Etymology: The subspecific epithet refers to the slender long leaves. Notes and Observations: This subspecies is distinctive in having glabrous fruits, green leaves and densely flowered inflorescences with small flowers. Some collections from Northern Territory differ shghtly in having wider leaves and very short dense inflorescence and laciniately lobed calyces. They were described as H. floribundum Pritzel, and have characters of both other subspecies. Further collections may prove it to be a distinct taxon, the collections seen so far are insufficient to form an opinion. Alectryon coriaceus (Benth.) Radlk. and A. semicinereus (F.Muell.) Radlk. The status of these two closely related species which were combined in the review of Alectryon by Reynolds (1983) is here reassessed in view of recent collections and the two species are shown to be distinct. When the genus was reviewed A. semicinereus was known from only one poor collection from north Queensland (Voick 1414) apart from the type and some cultivated specimens at ORS. It was not unlike some of the collections of A. coriaceus from south- 338 eastern Queensland so that it was thought to be an acute-leaved form of A. coriaceus and placed under that species. Both species have similar leaves, with greyish lower surfaces of leaflets, and the same indumentum, inflorescences, flowers and fruits. Recent additions to the collections from north Queensland show that the leaves of these specimens are distinct from those from south-eastern Queensland. Since the two species also differ ecologically, A. semicinereus 1s now considered to be a species distinct from A. coriaceus. The key to the species (Reynolds 1983, pp. 472-473) should be amended.

Guymer Queensland Herbarium, Meiers Road, Indooroopilly, Qld 4068 Summary The new species Notelaea pungens and N. lloydii are described and illustrated. During a collecting trip to the Barakula State Forest in November 1981, I collected fruiting material of a species of Notelaea which was unknown to me. Later examination of this material revealed that 1t represented a new species. However, I required flowering material to complete the study. This material has recently been obtained through the generous assistance of Mrs Val Hando of Chinchilla and enables the species to be formally described. The second Notelaea species described in this paper was brought to my attention by Mr L.H.Bird of Bundamba who first collected material of it in 1981. Subsequent collections by him and examination of populations in the field have confirmed that it, too, 18 a new species. __ Floral descriptions of the two new species are based on material preserved in Spirit.

Distribution: The species is known from the Mt Crosby area, on the western outskirts of the city of Brisbane and from the Boonah district, southwest of Brisbane. Ecology: N. /ioydii occurs in the ecotone between eucalypt open forests and vine thickets. The most common associated eucalypts are FE. crebra F.Muell. and E. maculata Hook. with associated trees and shrubs of Brachychiton populneus (Schott & Endl.) R.Br., Alphitonia excelsa R.Br., Acacia aulacocarpa Cunn. ex Benth., A. concurrens Pedley, A. falcata Willd., and Diospyros ferrea (Willd.) Bakh. var. geminata (Willd.) Bakh. Flowering period: June to early August. Fruiting period: October to December. Notes: N. floydii will key to N. microcarpa in Green’s (1968) revision of Notelaea and in the Flora of South-eastern Queensland (Stanley & Ross 1986) but can be distinguished from this species by its verruculose linear leaves, 5-—9-flowered inflorescences and multistemmed habit. Conservation status: The species is presently known from two locations sixty kilometres apart. The populations that occur on the Tyamolum Scout camp site and in Moggill State Forest (L.H.Bird, pers. comm.) are reasonably well protected from the encroaching urbanisation. However, N. //oydii is assessed as restricted and vulnerable (2V) using the sa one of Leigh, Briggs and Hartley (1981) until further distributional data are obtained. Etymology: Named in honour of Mr Lloyd Bird of Bundamba who drew my attention ‘to the distinctiveness of this species. Mr Bird is an avid botanical collector who has provided numerous specimens of botanical importance for the Queensland Herbarium, including N. /loydii.

New combinations are made for 228 species, 14 subspecies and two varieties. Most of the species were previously referred to Acacia Miller. The recognition of Acacia Miller subg. Phyllodineae Seringe as a distinct genus, Racosperma Martius (Pedley 1986), necessitates the transfer of most Australian species described as Acacia to Racosperma. Martius himself made only a few transfers. Racos- perma is reasonably well known in Queensland and now is an appropriate time to publish a list of species. _ Changes in the rank of some taxa are made but the circumscription of the great majority remains as before (see Pedley 1978,1980,1981,1987; Pedley & Forster 1986).

Pedley Queensland Herbarium, Meiers Road, Indooroopilly, Qld 4068 Summary Thirteen species of Racosperma Martius are naturalised in New Zealand and one is widely cultivated. These species, which were all formerly referred to Acacia Miller, are listed. New combinations are made for five of them, and for one variety. e The recognition of Racosperma Martius as a genus distinct from Acacia Miller (Pedley 1986) necessitates the transfer of many taxa to Racosperma. A few new com- binations were made by Martius in his validation of the name Racosperma (Martius 1835), and combinations for Queensland taxa are made in this volume (Pediey 1987), but a considerable number are still required. Thirteen species of Racosperma are naturalised in New Zealand and one is widely ~ cultivated (Webb 1980 & in litt. 1986). These are listed below. Naturalised Species Racosperma baileyanum (F.Muell.)

Bostock Botany Department, University of Queensland, St Lucia, Qld 4067 Summary Adiantum whitei Bailey (Adiantaceae), formerly recorded from a few localities in south-eastern Queensland, is now known to haye a wider range in north-eastern Australia. The receptacle of this taxon bears thick-walled trichomes, a condition not previously reported for the genus. 4. whiter is reduced to varietal status under 4. hispidulum Sw. The original collections of Adiantum whitei were from Kenmore, a western suburb of Brisbane. Other contemporary collections came from the nearby suburbs of Indooroopilly and Enoggera, Lawnton (One Mile Creek) ca 16 km north of Brisbane and Maryborough ca 215 km north of Brisbane. The last collection (other than cultivated specimens) appears to have been from Kenmore in December 1931 (AQ142926, BRI). Recent collections of Adiantum taxa include a robust tripinnate fern collected 9 km SW of the type locality (State Forest 494 Moggill, Bostock 190, BRI) which matches one of the syntypes of A. whitei (Kenmore, May 1915, White AQ24496 (BRI). A collection from ca 6 km NE of the type locality was subsequently propagated from its spores (R.Hill, pers.comm.). The descendants have been distributed under the horticultural names Adiantum aff. whitei and Adiantum sp. ‘S.E. Qld’. More recently A. whiter has been found to be common along creeks in the southern and western parts of Brisbane and specimens now in cultivation in Brisbane are reputed to have come from as far afield as Mt Spec ca 1500 km north of Brisbane (C.Ritchie, pers. comm.). A revised description of A. whitei is given here, based on specimens examined by the author. Rhizome short-creeping, semi-erect, stoloniferous; scales concolorous, with entire margins and acuminate apex. Fronds approximate, occasionally remote, to 60 cm long. Lamina to 30 cm long, 20 cm broad, triangular, 2- to 3-pinnate, herbaceous to coriaceous. Rachides invested with antrorse red-brown hairs. Pinnae numerous, narrow-triangular, simply pinnate in their apical half. Ultimate segments symmetric and cuneate-flabellate becoming dimidiate and rectangular to trapeziform towards apices of pinnae and lamina; distal margins shallowly lobed, dentate when sterile; segment surfaces invested with numerous short pale trichomes (to ca 0.4 mm long) and a few similar but longer ones, denser abaxially. Indusia crowded, | to 4 per lobe, oblong to subrectangular, joining the segment margin proper at a narrow sinus, bearing on their outer surface numerous dark brown uniseriate thick-walled trichomes, which are also scattered among the sporangia. Spores with minutely granulate perine adhering rather loosely to the exine. Fig. 1. Recent authors (Jones & Clemesha 1981, Elliot &-Jones 1982, Goudey 1985) have speculated that A. whitei is a hybrid. Jones and Clemesha (1981) and Goudey (1985) proposed A. hispidulum Sw. and A. formosum R.Br. as putative parents. Little evidence is offered in support of this statement, although Goudey (1985) lists a number of morphological characters of A. white? which are common to one or other of these species. In his original description and accompanying illustration, Bailey describes the rhizome of A. whitei as ‘creeping’. Investigation of the new collections has shown that the ‘creeping’ rhizome is a stoloniferous branch that on occasion bears fronds spaced a few centimetres apart. The apices of mature stolons bear a tuft of fronds indicating reversion to a short-creeping rhizome. In this respect, the rhizome ramification of A. whitel is similar to that of both A. hispidulum and A. aethiopicum L., another taxon FBetTocs. it8 Pipe Fon tee on . PP eh Sn Os zee nM, Fig. 1.

The symmetric and cuneate-flabellate ultimate segments of A. whitel are reminiscent of those of A. formosum and A. aethiopicum. However, A. hispidulum also bears segments of a similar form, as in the small accessory pinnae between the major bifurcations of the rachides in pedate forms, or in many (sometimes the majority) of the ultimate segments in pinnate forms. A. hispidulum sens. lat., which is found from eastern Africa, through India and Malesia to Australia and the western Pacific (Parris 1980), 1s a variable taxon. The form which occurs in drier areas in north- eastern Australia has pedate, sub-pedate or pinnate-bipinnate fronds, with texture and indumentum of the lamina as described above for A. whitei. It is this form which occurs in areas where A. whitei has been collected, and which is referred to in the remainder of this discussion. The range of frond forms which occur in A. whitei and A. hispidulum are shown as silhouettes in Fig. 2. Indusia of A. whitei (Fig. 1C) are morphologically identical to those of A. hispidulum in shape, location on the segment and nature of the trichomes investing the outer surface. Additionally, most specimens of A. whitei have been found to possess hook-shaped trichomes among the sporangia (Fig. 1E-F). Indusia of A. hispidulum occasionally bear trichomes just under their margins but trichomes have not been found to arise from receptacular tissue. The genus Adiantum is usually recorded as non-paraphysate (e. g. Tryon & Tryon 1982), although Nayar (1961) recorded club-shaped paraphyses for material identified as A. tenerum Sw. The observation of receptacular trichomes reported here 1s Heh first for the genus, and may be regarded as diagnostic of the taxon regarded as A. whitel, A, whitei and A. hispidulum cannot be separated by using any of the following characters: rhizome scales (4. whitei, Fig. 1D); lamina texture; rachis indumentum or texture; spore ornamentation; rate of spore germination (tested at room temperature (12-—24°C) with indirect natural lighting). They have similar ecological requirements, and are generally found in close proximity, although A. whitei, which grows mainly in the vicinity of watercourses appears to be less tolerant of dry conditions than A. hispidulum, which 1s often found in relatively sheltered places considerably distant from streams. On the basis of the above evidence, A. whitei Bailey is here reduced to the status of a variety of A. hispidulum Sw. Adiantum hispidulum Sw. var. whitei (Bailey) P.Bostock stat. nov.

(all BRI). Agamospory in the A. Aispidulum complex The source of taxonomic confusion in many fern species may be shown to result from agamospory. Thus the spores contain the unreduced parental chromosome com- plement and sporophytes arise directly from gametophytic tissue. Archegonia are absent from the gametophytes although functional antheridia are usually present (Walker 1983). This is the situation with Adiantum caudatum L. sens. strict., which is a member of a compiex consisting of at least seven taxa (Lovis 1977). Agamospory has also been reported as the normal state in A. hispidulum (Manton & Sledge 1954, Abraham et al. 1962, Ghatak 1977, Bidin 1983). The sole exception 1s Brownlie (1957, 1965) who reported only meiotic chromosome counts. At least 4 cytotypes have been identified in A. hispidulum (Walker 1983), but detailed studies linking morphology and cytology in the taxon are not available.

Bostock 1 364 In all investigated cases of hybrids between apomicts and sexual species (where the apomict must be the male or antheridial parent), the offspring have been apomictic (Walker 1979, 1983, 1985). The production of fertile spores by 4. whitei is not unexpected, even if the taxon should prove to be a natural hybrid between A. Aispidulum and another (sexually reproducing) Adiantum taxon. Walker (1985) commented on the ability of agamosporous taxa to build up extensive agamic complexes in this manner and the possibility that 4. whitei has its origins in such an event (or events) cannot be discounted. _ The numerous morphological similarities between A. hispidulum and A. whiteli indicate a common ancestry, but the latter taxon is sufficiently distinguished by virtue of its frond dissection and receptacular trichomes to be given varietal status.

Jackes Botany Department, James Cook University of North Queensland Townsville, Qld 4811 Summary The genus Cayratia Juss. is reviewed for Australian species. Two species C. maritima and C. cardiophylla are described as new. A description of the genus and of each of the eight species occurring in Australia is given, together with a key to the species.

Type: Cayratia pedata (Loureiro) Jussieu ex Gagnepain. Climbing or scrambling vines, slender, evergreen or deciduous, underground system sometimes tuberous. Tendrils leaf-opposed, often branched several times, each branch subtended by a bract. Leaves alternate, compound, 3—5-foliolate, pinnate or pedate, margins usually serrated. Stipules 2, caducous. Degree and type of pubescence on aerial parts varies between species. Inflorescence axillary, pseudoaxillary or leaf-opposed, pedunculate, carried above the leaves, multiflowered in irregular corymbose cymes, often loose; peduncles and pedicels subtended by bracts. Flowers bisexual, small, tetramerous, pedicellate, buds often swollen. Calyx cup-shaped or margins sometimes spreading. Corolla with 4 free lobes, cohering in bud by the interlocked epidermal cells, sometimes cucullate at the apex, reflexed after anthesis. Stamens inserted on the receptacle at the base of the disc, opposite the petals, filaments erect, often flattened, anthers introrse, dorsifixed opening by longitudinal slits. Pollen grains tricolporate. Disc adnate to and entirely surrounding the ovary, the 4 rounded lobes sometimes extending above the ovary. Ovary 2-locular with 2 anatropous, basally attached ovules per locule; style conical, stigma minute, expanding after anthesis. Berry fleshy with 1-4 triangular to ovoid seeds. Shape of seeds in transverse section varies according to the number maturing in the fruit, the flattened area on the dorsal surface formed by the perichalaza may be rounded or elongate, | or 2 furrows or pits are present on the ventral surface. Endotesta lignified sometimes with lateral flanges, endosperm ruminations in transverse section may be T- shaped or U-shaped. Mucilage cells and raphide sacs also often with mucilage, appear to be present in all organs. Cayratia may be distinguished from the closely related genus Cissus by the following characters: leaves compound, petiolules associated with the leaflets, ratio central petiolule to lateral petiolule rarely less than 2; inflorescence a dichotomous cyme, usually axillary or pseudoaxillary by the abortion of the lateral axis; endosperm in transverse section either T-shaped or U-shaped. Two of the characters by which Gagnepain (1911) and Latiit (1981) separated these two genera are not valid for Australian species. They considered that in Cissus the leaves are always simple and the berry is 1-seeded. Although leaf size, margin indentation and degree of pubescence exhibit considerable intraspecific variation, number of leaflets, shape and relative size, position of hairs, nature of the tendrils and seed characteristics are useful diagnostic characters. All measurements and observations in this paper refer to dried mature organs unless otherwise indicated. According to Galet (1967) there are about 63 species most of which occur in the tropical and subtropical areas of Africa, Asia, Australia and many of the Pacific Islands. 366 Eight species occur in Australia, three are endemic, and two are endemic to Australia and adjacent areas of New Guinea. The species in Australia fall into three separate sroups distinguished by leaf, fruit and seed characters. Key to the Species 1. Leaflets 3 .. Leaflets 5 .. . 2.

Specimens from 38 Australian localities were examined. Distribution and Habitat: This vine 1s commonly found growing along tropical coastlines (Map 1.) and adjacent areas which are seasonally inundated as well as around lagoons and along creek banks. It extends into Indonesia, New Guinea and neighbouring Pacific Islands. Soils are usually alluvial or sandy. Flowering period: spring to summer. Fruiting period: summer to winter. Notes and Observations: This species is readily distinguished from the related C. trifolia by the 3-fid tendrils which lack adhesive pads at the apices and by the mature leaves pias are glabrous except for hooked hairs on the adaxial midrib. Leaves usually dry dark grey. 2. Cayratia trifolia (L.) Domin, Biblioth. Bot. 89: 370 (1927). Vitis trifolia L., Spec. Pl. 203 (1753); Benth., Fl.

Distribution and Habitat: This species extends from India to the Pacific. In Australia it is found (Map 2.) chiefly in open forest in tropical regions usually climbing on trees with persistent bark. Soils are variable. Flowering period: spring to summer. Fruiting period: summer to autumn. Notes and Oservations: Leaf size, thickness, nature of the leaf margin and degree of pubescence are highly variable in this species. Hairs are always present on both leaf surfaces when young. Size of leaf appears to be related to habitat, those plants growing in moister, protected areas usually have the largest leaves. 3. Cayratia saponaria (Seem. ex Benth.)

Specimens from 18 localities were examined. Distribution and Habitat: This species is found (Map 5.) in rainforest or rainforest remnants from north of Cardwell 18°06’S, 146°02’E, to northern Cape York Peninsula. Flowering period: spring to summer. Fruiting period: summer to early autumn. Notes and Observations: The specimen selected as the lectotype 1s the more complete specimen of the syntypes upon which Bentham based his description. C. saponaria (Seem. ex Benth.) Domin and C. seemanniana A.C.Smith have been confused in the literature as both species were based on the name Vitis saponaria. However as indicated by Smith (1942) these are two different species and the latter may be distinguished by ‘the persistent tufts of hairs in the axils of nerves on the lower surface’. He also considered the leaflets to be thinner and the iateral leaflets to be more cordate at the base; however these are very variable characters. | The description of Cissus bicolor Domin does not agree with the specimen cited as the type. The leaves of this specimen (Domin 6373, 6374, PR) and of the illustration (Domin 1927, p923) are in fact the leaflets of Cayratia saponaria. 4. Cayratia cardiophylla B.R.

Specimens from 39 localities were examined. Distribution and Habitat: This vine, which is usually decidous, is commonly found growing over beach rubble, along river edges and in semi-deciduous vine thickets, rarely in rainforest. In appears to prefer limestone based soils and coral rubble. It is found in North Queensland and the Torres Strait (Map 3.) chiefly on coral islands and around Chillagoe. Flowering period: August to December. Fruiting period: November to May. Notes and Observations: Several sterile senescing specimens from Western Australia and Northern Territory have been provisionally placed in this species on the basis of leaf pubescence and shape, however further collections preferably obtained before the onset of the dry season are required for clarification. This species which is closely related to C. acris may be distinguished by a number of characters: the length/breadth ratio of the central leaflet is 0.96 + 0.12, compared with that for C. acris (1.47 + 0.4); the filaments are much narrower; 1-3-celled hairs are present at the junction of the style and the top of the ovary, as well flowering occurs on new growth before the leaves have fully expanded. This species also appears to flower more frequently if the number of flowering specimens in collections is any indication. However sterile senescing specimens cannot be assigned absolutely to either species. This species has been previously misidentified as C. grandifolia, however the type specimen of this species is less pubescent, although flowers in reasonable condition were unavailable, the leaves on the specimens were fully expanded. §.

Distribution and Habitat: Found from Northern New South Wales to the tip of Cape York, Queensland, (Map 4.) and into New Guinea as well as isolated localities in the Northern Territory. It is found chiefly in rainforest and to a lesser extent in semi- deciduous vine thickets and riverine gullies. This species appears to be deciduous under marginal conditions. Flowering period: October-—May. Fruiting period: March. Notes and Observations: This species occurs in New Guinea where it was described as Cissus grandifolia by Warburg (1894). Careful examination of Hellwig 125 (K) marked ‘det. by Warburg’ and Branderhorst 142 (K) cited by Lauterbach (1925) failed to separate this material from specimens of C. acris. Unfortunately the material is scrappy and as the majority of specimens of C. acris are vegetative, confusion has existed between this species and C. cardiophylla which has till now been misidentified as C. grandifolia. Merrill and Perry (1941) noted ‘that the pubescence on the lower surface of the leaves is confined to the midrib and the larger nerves’, whereas Warburg (1894) described the lower surface as pubescent. 6.

Windolf 53 Pandanus Avenue, Coolum Beach, Qld 4573 Summary A checklist is presented of all current binomials known from Queensland, together with synonyms relative to Queensland specimens or literature dealing specifically with such specimens. Footnotes are employed to expand on points of particular interest and a table of distributions is given, based on a proposal using four regional divisions. Genera in the checklist are numbered consecutively and are cross-referenced to an alphabetical index of genera. Notes on the history of hepatic research in Queensland and on the principal collections of Queensland Specimens are also included. History of hepatic research in Queensland Throughout approximately 150 years of European settlement in Queensland, up to the 1970’s, hepatic research has been confined to very limited collecting both in terms of the number of specimens obtained and the geographical area covered (Everist 1982). This work was undertaken by no more than a dozen people who, apart from one or two exceptions, were not directly involved with nor had any particular interest in hepatics as such. Only within the last decade has any comprehensive approach been attempted and as a result our understanding of the species present, their distributions, habitats, ecological peculiarities and affinities with overseas taxa is still very much in the formative Stage. The first positive mention of Queensland hepatics was made by F.M. Bailey soon after he became Colonial Botanist in 1881. Bailey was a man of almost unlimited energy and he found time to indulge an interest in the lower plants as well as carrying out his more formal work assignments. Most of his collecting was done in south-eastern Queensland but he made one trip to the northern Queensland rainforests of the Bellenden Ker Range area which resulted in a considerable number of new taxa being discovered. Other collectors of hepatics at this time include C.J. Wild, C.J. Gwyther, J. Shirley and J.H.Simmonds. Apart from listing the taxa found, Bailey did not systematically study the local hepatic flora. Most specimens were sent overseas for identification, the majority to Stephani in Leipzig, East Germany who retained any types and specimens of particular interest. Since Bailey’s work at the turn of the century virtually no interest was taken in hepatics for over 60 years. During 1963/64 Dr H.J. Hewson, Bureau of Fauna and Flora, Canberra, made extensive collections of Aneura and Riccardia in northern Queensland as a foundation for her revision of the family Aneuraceae in Australia and New Guinea (Hewson 1969, 1970). In the late 1970's a few visiting bryologists, realizing that Australia and in particular Queensland contained a vast storehouse of understudied material, did some minor collecting. However, most amounted to little more than one or two day recreational type excursions and largely covered the same ground as Bailey and his associates nearly a century before. It is only within the last six years that properly organized, extensive collecting has been undertaken. From 1980 onward I have system- atically collected the area between Brisbane and Rockhampton and have lodged checklists with the Queensland Herbarium (BRI). I have studied habitat and ecological relationships in some environmentally significant areas and also reviewed and collated the collection of the Queensland Herbarium. Other notable collections have been made by Dr Marie L. Hicks of the Appalachian State University, in the rainforest belt between Tully and Daintree and Dr Barbara M. Thiers of New York Botanic Gardens in preparation for her pending review of the family Lejeuneaceae in Australia. In spite of the limited amount of time and effort that has been expended on Queensland hepatics, a relatively comprehensive catalogue of taxa is now known, drawn mainly from the South and North Coast Regions (Map 1.). This paper aims to present such information as is currently available in the hope that it will help stimulate interest 38] in further collecting, particularly in the more neglected areas such as the Central Coast Region, Cape York Peninsula and the Gulf Country. Collections of Queensland Hepaticae The Queensland Herbarium collection numbers about 650 specimens of Australian hepatics, over half of which date from last century. Many of these are in poor condition and very few are suitable for serious taxonomic work. Approximately one third of the early collections are from interstate, having been supplied to Bailey for comparative purposes. Many were not clearly marked and it is often difficult to tell which are Queensland specimens. Hewson provided the Herbarium with some 80 specimens of Aneura and Riccardia following her collecting in the 1960’s, among them several isotypes. The majority of the recent acquisitions were donated by me, and I also maintain an extensive personal collection of Fru/lania as well as representative specimens of other Queensland species. Overseas herbaria which contain sizable collections of Queensland material include the Cryptogamic Herbarium, New York Botanic Gardens, New York, U.S.A. (NY), Appalachian State University, Boone, North Carolina, U.S.A. (BOON), and the Her- barium of the Hattori Botanical Laboratory, Nichinan-shi, Japan (NICH). Duplicates of many of my specimens have been sent to these institutions. The Conservatorie et Jardin Botaniques, Geneva, Switzerland (G) houses the many type specimens of endemic Queensland species which were included in the Stephani Collection. Total geographical area covered The total area covered comprises the political entity of the State of Queensland which includes the Torres Strait Islands, the various islands and cays of the Great Barrier Reef, the offshore islands of the southern coast such as Curtis, Fraser, Moreton, Stradbroke, etc., as well as the islands in the Gulf of Carpentaria east of the longitude of the Queensiand/Northern Territory border (Map 1.). Regional divisions For the purposes of depicting distribution patterns, the overall area is divided into four regions based on physical and climatic characteristics (Map 1.). In line with the Bureau of Meteorology (1977) regional classification based on rainfall, the initial division corresponds to the easternmost watershed created by the Great Dividing Range and forms the boundary between the Coastal and Inland sections. Preliminary studies show that to the east of this line, the hepatic population is primarily dominated by moisture loving taxa of the Order Jungermanniales, while to the west there is a limited range of species drawn from what are generally regarded as the xeromorphic genera (Targionia, Riccia, etc.) of the Order Marchantiales. The Coastal section is further subdivided into three regions, the South Coast, Central Coast and North Coast. The boundaries between these regions are in the vicinity of Rockhampton and Ayr and again correspond to those of the meteorological districts. There does not seem to be any justification in further sub-dividing the Inland section. The wetter areas supporting the most diversified and prolific hepatic flora tend to occur towards the centre of each coastal region, while the boundary areas equate closely with belts of lower rainfall. As a result the number and range of taxa in the vicinity of the boundaries is small, thus suggesting the concept of natural hepatic regions corresponding to the regional divisions of the State proposed here. Arrangement of the checklist The classification employed in the arrangement of the checklist is that of Schuster (1979). The primary reasons for choosing this system are: a. It is based on widely accepted, modern views regarding the evolution of the Hepaticae. b. Detailed descriptions of the taxa are in readily available publications. c. It lends itself to herbarium use in that it is compatible with other systems already established in various overseas herbaria. 382 In this system Schuster set down seven Orders within the Hepaticae. Of these only three have been reported from Queensland: Jungermanniales, Metzgeriales and Marchantiales. The checklist is divided into sections corresponding to these Orders and 1s then further subdivided according to Schuster’s arrangement for families and genera. The names of the Orders are in BOLD CAPITALS and the names of families and genera are in bold Upper and lower case. Species and any subspecific taxa are subsequently arranged alphabetically. Taxa reported in recognized literature or known to exist aS specimens are consid- ered legitimate. Synonoms relative to Queensland specimens or names under which these specimens have been recorded are given in italics immediately beneath the current name. Specimen references are given for all taxa cited as sp. All genera in the checklist are numbered consecutively with the numbers cross- referencing to the alphabetical index of genera following the checklist. Abbreviations used in the checklist STH(S) South Coast Region CNT(C} Central Coast Region Species reliably reported to occur in that region. NTH(N) North Coast Region INL(I) Inland Region ? Report of species in that particular region is either not considered reliable or the locality is not positively known and its occurrance in that region is presently tentative. + Little is known about the reported occurrance of this species in Queensland and its inclusion should be treated cautiously pending further investigation. 12.3: Cross-reference numbering, for genera. (1) (2) Footnote numbering. Reliability of information As many reports of Queensland hepatics date back almost a hundred years and are often contained in obscure and difficult to obtain literature, not all have been personally investigated. In some cases it has been necessary to resort to second-hand information but every attempt has been made to ascertain the reliability of all data used. Only comprehensive revisions of families and genera involving detailed comparative studies with overseas specimens can resolve the many taxonomic and nomenclatural problems which remain. A list of the literature used in compiling the checklist is given in Appendix A.

(7) Grolle (pers. comm.) asserts that Noteroclada does not occur in Australasia and so the numerous reports of this species over the years are obviously misidentifications. Subsequent examination of numerous Queensland specimens dating back to 1885, show that most, if not all, are in fact Lethocolea squamata. (8) Practically nothing is known regarding Queensland species of Schistochila. Schuster and Engel’s revision of Schistochila should help clarify most points when it 1s completed.

(9) Based on a single specimen collected last century by F.M. Bailey and now held in the Queensland Herbarium. It is minute and in very poor condition but appears to be as determined, apparently by Stephani. In addition Hattori (1979b) notes that the type of Frullania fissistipula Steph. (from Bellender Ker, North Queensland) is in fact a species of Lepidoleana but he gives no further details. 390 Jubulaceae 30. Fruilania Raddi F, allani Hodgs.

(11) Frullania exigua is almost certain to be a misidentification but as no specimen has ever been found which equates with the report made by Bailey in 1890 it is impossible to say what the species in fact was. (12) Bailey’s record of Frullania fugax in Queensland (1888) seems to be based on a specimen that is very similar to the one that was later (1910) described by Stephani as Frullania baileyana but the point needs further study. (13) The status of Frullania probosciphora-F. reptans synonomy and the occurance of the species in Queensland IS uncertain. 391 F. queenslandica Steph. F, rostrata (J.D.Hook. & Tayl.)

P.I. Forster Botany Department, University of Queensland, St Lucia, Qld 4067 Summary The new combination Gymnema dunnit based on Marsdenia rostrata R.Br. var. dunnii Maiden & Betche is made. The species is described and illustrated with notes given on distribution, habitat and conservation status. During studies of the Australian Asclepiadaceae, 1t became evident that material originally described as Marsdenia rostrata R.Br. var. dunnii Maiden & Betche was referable to the genus Gymnema. While there is some superficial vegetative similarity to Marsdenia rostrata, the floral characters of this taxon are those of Gymnema both in the narrow sense of Huber (1983) and the broader concept favoured by Schiechter (1914). This incorrect generic placement has been recognised by several workers (Jacobs & Pickard 1981, Willams & Harden 1981, Stanley & Ross 1986) but no attempt has been made to effect the necessary transfer. Hence, the following new combination and change of status is made. Gymnema dunnii (Maiden & Betche) P.Forster, comb. et stat. nov. Marsdenia rostrata var. dunnii Maiden & Betche, Proc. Linn. Soc. New South Wales 31: 736 (1906). Type: New South Wales: Acacia Creek, McPherson Range, Dec 1905, J.L.Dunn (holo: NSW; iso: BRI AQ333081). In the original description of Marsdenia rostrata var. dunnii, Maiden & Betche (1906) incorrectly cite the type as ‘Mrs. J.L. Dunew’. Woody vine. Stems puberulent, twining, 1-1.5 cm thick; with coarsely fissured bark, corky, grey-brown, dark-brown when cut; with white latex. Leaves ovate, oblong-ovate to oblong-elliptic, apex acute to acuminate. base obtuse to cuneate, 2.5—8 cm long, 1.3~—10.5 cm wide, yellowish-green to green above, paler beneath, finely puberulous on both surfaces with lateral and reticulate venation more prominent on abaxial surface. Petioles 0.6-4 cm long; 5-9 extra-floral nectaries present at midrib base of lamina. Stipules at either side of petiole base. Inflorescence an extra-axillary umbel with up to 7 flowers, 1(2) umbels per node; peduncles 0.3-1.2 cm long; pedicels 2-5 mm long, finely pubescent. Calyx 1.5~2 mm long, subacute to oblong, lobed from 1/2 to 3/4 length, sparsely pubescent externally. Corolla convolute; lobes acute to oblong, reflexed at anthesis, glabrous outside, sparsely shortly pubescent inside, 2-2.5 mm long; tube 2-2.5 mm long, shortly pubescent inside; corolline corona of thickened ridges running longi- tudinally down tube and alternate with lobes, densely pubescent on edges. Staminal column 2~2.5 mm long; corona consisting of small discrete tubercles at base; anthers with membranous tip, anther groove 0.9—1.1 mm long. Ovaries glabrous: stigma conical, 2-2.5 mm longer than staminal column. Pollinium ascending, without pellucid margin, oblong, golden, ca 140-150 um long. Translator dark brown, ca 100 um long. Caudicle without wings, ca 47 um long. Follicles fusiform, 5-6 cm long. Seed light-brown, 7-8 mm iong, 2-3 mm wide; coma white, 15-20 mm long.

Map 1. Habitat: Gymnema dunnii occurs primarily in semi-evergreen vine thickets or araucarian microphyll and notophyll vine forests (dry deciduous rainforests) on a variety of rock types from 200-700 m altitude. Plants are usually infrequent at the localities visited, usually consisting of up to a dozen large clumps (although the population 2.5 km SSW of Gladfield was extensive). The vegetation communities are usually open with high light levels and it is uncommon to encounter juveniles in heavily shaded conditions. Often the species may be found associated with other Asclepiadaceae such as Sarcostemma australe R.Br., Secamone elliptica R.Br., Gymnema micradenium Benth., Marsdenia leptophylla F.Muell. ex Benth. and species of Parsonsia (Apocynaceae). Conservation status: Given the destruction of much of the dry deciduous rainforest communities in Queensland and north-eastern New South Wales, it may be assumed that the distribution of G. dunnii is less extensive than in the past. The localities visited were usually regrowth remnants and unlikely to survive in the long-term. While it has been recorded from at least one conservation reserve, there does not appear to be an adequate representation throughout the species range. The plant 1s inconspicuous and when sterile unlikely to be collected and probably occurs at other sites within the range indicated. At this stage G. dunnii should not be considered endangered.

Johnson Queensland Herbarium, Meiers Road, Indooroopilly, Qld 4068 Summary Two species of Convolvulus, C. eyreanus and C. microsepalus are described as new. They are currently known only from South Australia. In preparing an account of Convolvulus for the Flora of South Australia (Johnson 1986), two taxa, which appeared to be undescribed, were segregated from the highly variable material grouped under C. erubescens Sims. Prior to the publication of Flora Australiensis Vol. [V (Bentham 1869), eight native taxa had been recognised but Bentham chose to incorporate this variation within C. erubescens. This species was originally described from a plant of New South Wales origin cultivated in 1806 in the Royal Botanic Gardens, Kew. Since the release of the Flora of South Australia, type specimens - of most of these taxa have been studied and none 1s representative of the two taxa described in this paper.

Distribution: It occurs throughout the north-eastern parts of South Australia in the basins of Lake Eyre, Lake Torrens and Lake Frome. Ecology: It has been recorded from sand dunes and on gibber plains in desert regions. Flowering and Fruiting: Flowering occurs mainly in spring and early summer but flowers can occur at most times of the year. Fruiting begins in the late spring. Affinities: It most closely resembles C. clementii Domin but is clearly distinguished by its dense silvery indumentum, and more serrate and more shallowly-lobed leaves. It differs from C. erubescens Sims in having much smaller flowers, with petals less than 10 mm long. In the northern parts of the Eyre and Yorke Peninsulas is a form with small, serrate, silvery leaves which may prove taxonomically distinct. Etymology: The specific epithet refers to the name Eyre in Lake Eyre and the Eyre region of South Australia, both named in honour of Edwin John Eyre (1815-1901), explorer.

Ecology: It grows in chenopod shrublands on sandy plains. Indications from the few specimens collected are that it is not of common occurrence. Flowering and Fruiting: The main flowering period is during the spring to early autumn but occasional flowers have been recorded at other times. Capsules are produced from the late spring onwards. Affinities: It most closely resembles C. remotus R.Br. in leaf-shape and indumentum. However the sepals of C. remotus are about twice as long, are apiculate, not + emarginate, and are hairy. The flowers of C. remotus are also much larger. The sepals of C. microsepalus most closely resemble those of C. arvensis L. but the latter has a corolla at least twice as large. C. erubescens also has a much larger calyx and corolla. Etymology: The specific epithet refers to the size of the sepals which are by far the smallest for any species of Convolvulus recorded from Australia. References BENTHAM, G. (1869).

AND A NEW RECORD OF DAVIESIA SMITH (FABACEAE: MIRBELIEAE) FROM QUEENSLAND M.D. Crisp Australian National Botanic Gardens GPO Box 1777, Canberra, ACT 2601 Summary Isotropis foliosa is described as new and distinguished from its relatives. It is restricted to two known localities in south-eastern Queensland. A key to Queensland species of Isofropis is provided. The discovery in Queensland of Daviesia arthropoda F.Muell., a central Australian species, is reported. Isotropis Benth. is a genus of about a dozen species distributed in western, central and north-eastern Australia. Although belonging to the endemic Australian tribe Mir- belieae, the genus is somewhat anomalous, and its position within the tribe is uncertain (Crisp & Weston 1987). During a recent visit to the Queensland Herbarium, my attention was drawn to an apparently undescribed species of Jsotropis. Subsequent examination of a population in the field confirmed its novel status. The newly discovered species, while showing all the essential characters of [sotropis, is remarkable in two respects. One is that it extends the known range of the genus to the south in eastern Australia. The other is that its leaves are more developed than those of any of its congeners.

MORETON DistRIcT: D’Aguilar Range, ca 13 km NE of Ipswich, between Kholo Creek and Wirrabara Road, 5 km E of Mt Crosby summit, 27°32’S, 152°32’E, Aug 1986, Crisp 7834 & Telford (BRI,CBG, K), Crisp 7835 & 7836 (CBG), foothills of D’ Aguilar Range, 4km S of Mt Glorious, 27°20, 152°49’E, Sep 1982. Young 611 (BRI!; K,LE,;SMEXU,MO,NSW,SP n.y.). Habitat: On foothill slopes vegetated by tall open eucalypt forest. At the type locality, the population is scattered over a steep west-facing midslope, on skeletal to very stony clay-loam. The dominant trees include Eucalyptus maculata, E. microcorys, E. intermedia, grey gums, ironbarks and Lophostemon confertus. The understorey 1s mostly dominated by Imperata cylindrica. Affinities: [sotropis foliosa differs from all other species in the genus in its manifestly leafy appearance. To some extent, it resembles the central Australian J. atropurpurea, which has a comparable habit and similarly shaped leaves. However, J. atropurpurea differs in being conspicuously tomentose, rather thick in all its vegetative parts, and in having smaller flowers (8-10 mm lon ). There are four other species of Jsotropis in Queensland: f. fAlicaulis Benth., I. parviflora Benth., I. wheeleri F.Muell. and I. winneckei F.Muell. None has flowers more than 10 mm long and all have inconspicuous, narrow (mostly linear) leaves. Conservation status: Endangered, coded 2E (criteria from Leigh eft a/. 1984). As this species is known from only two very small populations, 1t must be considered endangered. In the Mt Glorious area, it was ‘recorded from only one very small area’ (label of Young 611). At the type locality, the population consists of perhaps 50 plants. It is in State Forest, subject to management practices such as logging and prescribed burning. In fact, the site had been fired within the previous few months; fortunately, the plants of J. foliosa were sprouting from their rootstock. A Scout camp adjacent to the type locality puts additional pressure on the population. Cuttings have been taken with the intention of establishing the species at the Australian National Botanic Gardens. Etymology: The specific epithet is Latin, meaning leafy. In J. foliosa, the leaves are larger and more obvious than in any other species of Jsotropis, many of which have leaves reduced to phyllodes. Key to Queensland species of Isotropis 1.

Type: In monte Olgae, E.Giles (holo: MEL). | This is a rare species of central Australian sand dunes. Until recently, it had been recorded only from the south-western corner of the Northern Territory, the immediately adjacent part of Western Australia and the Maralinga area in South Australia (Crisp 1981, Weber 1986). Now, an old unidentified collection by S.T. Blake from western Queensland has been located in the perm Herbarium. The material, which is in fruit, appears typical for D. arthropoda and comes from the usual sand dune habitat. This find is remarkable because it represents an extension of some 1000 km to the known range of what is still a rare plant. Daviesia arthropoda is closely related to D. ulicifolia. For a key, descriptions and illustrations of these species, see Crisp (1981) or Weber (1986). Queensland.

Armstrong (1975) admitted Paramignya trimera (Oliver) Burkill to the Australian flora, stating that it was known ‘only from the Montague Sound area of northern W.A.’ He followed George & Kenneally (1975) who recorded it as new for the flora of Western Australia. Armstrong also noted the confusion about the taxonomic status of Atalantia in Australia. Burkill (1931) satisfactorily distinguished Atalantia from Paramignya on characters of the fruit, but fruits are not often available on herbarium specimens. Notes and drawings at the Queensland Herbarium made by C. T. White at Kew in 1939 indicate that Atalantia recurva Benth. is conspecific with Paramignya trimera. The synonymy Is: Paramignya trimera (Oliver) Burkill, Gardens’ Bull. 5: 212 (1931). Atalantia trimera Oliver, J. Proc. Linn. Soc., Bot. 5. suppl. 2: 23 (1861). Atalantia recurva Benth., Fl. Austral. 1: 370 (1863). Collectors have described the plant as a tree to 8 m, a shrub or a liane with greenish-yellow, cream or white fragrant flowers. It occurs in ‘dry scrubs’ (monsoon forest, deciduous vine thicket, semi-deciduous notophyll vine thicket) on coastal sands and, in Western Australia, on lateritised basalt. It ranges from the Kimberley region of Western Australia to Groote Eylandt. It has not been recorded from Queensland but can be expected on the west coast of Cape York Peninsula.

Walters et al. pp. 430 & xv. Cambridge: Cambridge University Press. 1986. This is the second volume of the Flora to be published. The first (Volume 2) which covers the remainder of the monocotyledons was published in 1984. The Flora attempts to provide a scientifically accurate and up-to-date means for the identification of plants cultivated for amenity in Europe and promises to be a worthy complement to Flora Europaea. Comparisons with Flora Europaea are inevitable as the two are similar in many ways. As well as having the same publisher it has an editorial committee of a dozen well known British botanists with seven equally well known advisers from seven countries of continental Europe. A bias towards plants grown in the British Isles might be expected as all but one of the 33 contributors.to this volume are based there. The Flora has been well planned. The aims of the work and its format are discussed 1n some detail in four introductory pages. Families and higher groups are arranged in the Engler and Prantl system as expressed in Melchior (edition 12). Other more modern systems are available but since the Engler and Prantl system has been so widely used, compatibility with other works 1s assured. All taxa are fully described except for some that are closely allied to described ones. A shorter diagnostic description is given for these. Keys to families, genera and species are provided. As well as the formal keys an ‘informal’ key is given for most large groups of species. These are in fact multiaccess keys and are useful in identifying infertile material. The contributor of each genus is acknowledged. The sequence of species within genera appears to be at the whim of the contributor. In Juniperus (contributor: H.J. Welch) the 19 species are arranged in the order they appear in the key. On the other hand the 18 species of Yucca (J. Cullen) key out in the following sequence: 18, 16, 12, 17, 8, 9, 10, 2, 15, 1, 4, 14, 2, 3, 6, S. The species are not arranged alphabetically. Perhaps the editorial committee could look at this point in future volumes. Of particular value are the references to taxonomic books and articles cited for each genus and family. Some of the lists are quite long. For example, for Galanthus there are 11 references covering the period 1894 to 1982. Authors of all names of taxa at and below genus level are given. The problem of abbreviatin authors’ names has been recognised and neatly solved. Instead of following the Drafi index of author abbreviations compiled at... Kew with all its quirks, as has been done in the Flora of Australia, the editors have given authors’ surnames in full without initials. Exceptions are some common names such as Brown, Foster and Smith. I wonder why there are so many botanical Smiths and so few Joneses. The need to simplify author citation has also resulted in the omission of those awkward and useless exs and ins. Instead of, for example, (Lindley in Mitchell) F.Muell ex Benth. we get (Lindley) Bentham. The practice is in accordance with the International Code of Botanical Nomenclature and might be adopted with profit by editors and authors generally. Synonyms and misapplied names are given with the accepted name. Because of the difficulties of providing vernacular names in all the necessary languages they are not included. It could be argued that, since the text is in English, vernacular names in English could have been provided. Illustrations in the Flora are limited to clear line drawings emphasising characters useful in identification and to silhouettes of fern fronds. There are some good diagrammatic illustrations in the glossary. References to good published iliustrations are also given. Many of these are to publications, such as Botanical Magazine and Botanical Register, not readily available in Australian libraries. For Australian genera such as Eustrephus, Geitonoplesium and Anigozanthos, however, references are made to modern Australian works. The book is remarkably free from errors, but among the Australian references I found C.A. Gardner’s name spelt wrongly. The design of the book bears comment. As in Flora Europaea the volumes are large with pages 275 mm X 220 mm. The typeface is neat and the text is easy to read, possibly because of the sparing use of italics and bold face. The introductory text is arranged in two columns, right hand justified. The effect is pleasing. The main body of the text, however, is arranged in three columns, not right-hand justified with ragged edges. The effect is not pleasing at all. 418 So much for the content and layout of the volume. Does it work? In south-eastern Queensland where one of the more aggressive weeds of gardens is Nephrolepis exaltata which is given a Flora hardiness rating GI (‘needs a cool glasshouse even in southern Europe’), finding plants to test keys and descriptions 1s dificult. Ferns are the exception. Many species are grown in glasshouse in Europe and out of doors here. They can be identified from the Flora without much difficulty. The illustrations are a great help. Delving into other families, Iridaceae, Agavaceae and Cupressaceae, proved equally rewarding. It is surprising that Callitris is not cultivated in European gardens. C. monticola, and, perhaps, C. baileyi and C. oblonga would make good tub plants in cool glasshouses 1n southern Europe. The European Garden Flora is a well presented, easy to use, scholarly work highly recommended to serious horticulturalists particularly in temperate regions. Two volumes have been published and another three or four will probably be needed to treat the dicotyledons. The work may therefore prove rather too expensive for most people. What is urgently needed is a work similar to L.H. Bailey’s Manual of Cultivated Plants, still a most useful volume though last revised more than 35 years ago. L.

Hampson, Government Printer, Queensland—1987 H-182 Notes for Authors Austrobaileya publishes original papers in systematic botany and related fields. Preference will be given to papers relating to the flora of Queensiand. All papers are refereed and the editorial committee reserves the right to reject papers. Manuscripts must be submitted in duplicate to The Editor, Austrobaileya, Queens- land Herbarium, Department of Primary Industries, Meiers Road, Indooroopilly, Qld 4068. They must be typewritten, double-spaced, with 2.5 cm margins and no underlining. All illustrations should be submitted with the text. For style and layout the most recent number of Austrobaileya should be followed: in particular the use of subheadings for distribution, etymology, etc. Where possible illustrations should be submitted in a size suitable for reproduction without reduction in size. The maximum size of a printed illustration is 12.5 cm x 18.5 cm. Do not put lettering on the illustration but indicate separately on a photocopy or overlay. The illustrations should be cited in the text and have brief easily understood captions. A typed list of captions must be supplied. All illustrations, both line drawings and photographs are to be numbered as figures in a common sequence. Published illustrations remain the property of the Queensland Herbarium. Tables should be as simple as possible. Long and/or complicated tables should be avoided. The tables should be numbered consecutively and each should be cited in the text. Titles of journals cited in the text should be abbreviated according to Botanico- Periodicum-Huntianum (Hunt Botanical Library, 1968) while names of books should be abbreviated in accordance with F.A. Stafleu and R.S. Cowan, Taxonomic Literature, edn 2(W. Junk, 1976-_ ). In bibliographies the titles of both journals and books should be given in full. The author should check to ensure that all entries in the bibliography are referred to in the text and all references to papers or books in the text are entered in the bibliography. Use author abbreviations as listed in Draft Index of Author Abbreviations compiled at the Herbarium, Royal Botanic Gardens, Kew (HMSO, 1980).
