Swainsona thompsoniana R.W.Davis & P.J.H.Hurter is described here as new. An amendment to an existing key for Swainsona Salisb. is provided to account for S. thompsoniana. Swainsona thompsoniana occurs on cracking clay soils from east of Pannawonica to Mount Florence Station and south-east to Tom Price and Wittenoom; a distribution map is included.
Solanum zoeae (Solanaceae), a new species of bush tomato from the North Kimberley, Western Australia
Recent surveys in the North Kimberley have brought numerous new species to light. Studies have revealed considerable taxonomic complexity in the genus Solanum L. in the Kimberley region that requires the recognition of a number of new taxa. Solanum zoeae R.L. Barrett is described here following collection of the first fertile material on a remote sandstone outcrop on Doongan Station. Notes are provided on all phrase-named Solanum taxa currently recognised in the Kimberley region and a revised key to Solanum species in the Kimberley region is provided.

Four new species of Astroloma R.Br. s. str. (A. acervatum Hislop & A.J.G.Wilson, A. chloranthum Hislop & A.J.G.Wilson, A. inopinatum Hislop and A. oblongifolium A.J.G.Wilson & Hislop) are described, illustrated and mapped. The current taxonomic status of Astroloma is discussed in the light of significant changes that are pending in the Styphelia clade to which the genus belongs. A key to members of Astroloma s. str. with pale yellow, cream and/or green flowers is provided.
A revision of the Australian species of Eclipta (Asteraceae: Ecliptinae) with discussion of extra-Australian taxa
ORCHARD, A.E. AND CROSS, E.W., Nuytsia23: 43–62 (2013)
The genus Eclipta L., of six species, is native to South America and Australia, with one species, E. prostrata (L.) L., a pantropical and warm temperate weed. The number of taxa currently recognised in the genus is discussed. The Australian taxa, comprising three species and two subspecies (E. prostrata, E. alatocarpa Melville and E. platyglossa F.Muell. subsp. platyglossa and subsp. borealis E.W.Cross & Orchard, subsp. nov.) have been studied morphologically across their full range. A lectotype is chosen for E. platyglossa. All Australian taxa are keyed, described, illustrated and mapped, and extra-Australian taxa are keyed and described, and most illustrated.
Allan Cunningham’s Timor collections
ORCHARD, A.E. AND ORCHARD, T.A., Nuytsia23: 63–88 (2013)
The visits of Allan Cunningham to Timor in 1818 and 1819, at the conclusion of Lieutenant Philip Parker King’s first and second survey voyages to the north coast of Australia, are summarised, and surviving collections held in the Natural History Museum herbarium and the herbarium, Royal Botanic Gardens, Kew are listed. The significance of the various labels found on these sheets is discussed.

Cochlospermum macnamarae (Bixaceae), a rare, new endemic from the Pilbara bioregion of Western Australia
HISLOP, M.,THIELE, K.R. AND BRASSINGTON, D., Nuytsia23: 89–94 (2013)
A new species of Cochlospermum Kunth, C.macnamarae Hislop, K.R.Thiele & Brassington, is described, illustrated and mapped. It occurs in the semi-arid Pilbara bioregion of Western Australia, unlike the other Australian species which all occur in the wet-dry tropics. A revised key to the genus in Australia is provided to accommodate the new species.
‘There are greater things in life than cricket’: Tetratheca aphylla (Elaeocarpaceae), James Drummond and the exploration of the Helena and Aurora Range
GIBSON, N. AND BUTCHER, R., Nuytsia23: 95–99 (2013)
Two Western Australian species currently referred to the genus Ozothamnus R.Br. have in the past been considered poorly aligned with that genus, but their alternative placement has been uncertain. Recent molecular studies have suggested that they are best placed in the Western Australian endemic genus Pithocarpa Lindl. The following new combinations are made: Pithocarpa cordata (DC.) Schmidt-Leb. & R.L.Barrett and Pithocarpa ramosa (DC.) Schmidt-Leb. & R.L.Barrett. Four species are now recognised in Pithocarpa and all are listed here. A key to the expanded genus is provided. Scanning electron micrographs are provided for a range of features for all taxa.

LANDER, N.S. AND HURTER, P.J.H., Nuytsia23: 109–115 (2013)
A new species of Asteraceae, Pleurocarpaea gracilis Lander & P.J.H.Hurter, is described from the Pilbara region of Western Australia. A key to all three species now included in Pleurocarpaea Benth. is provided.
Pilbara, a new genus of Asteraceae (tribe Astereae) from Western Australia
A new monotypic composite genus endemic to the Hamersley Range of Western Australia is described and the new species Pilbara trudgenii Lander is illustrated and mapped. Its affinities within the tribe Astereae Cass. are discussed. The new species is an obligate lithophyte.
Review of infraspecific taxa in Ptilotus gardneri and P. lophotrichus and lectotypification of P. conicus (Amaranthaceae)
The informal taxonomic subgroup typified by Solanum sturtianum F.Muell. comprises those species that have stellate hairs, black mature fruits with a thin brittle pericarp, and brown to black seeds. The subgroup is endemic to Australia. Ten species are recognised here: S. sturtianum is maintained, S. morrisonii Domin is reinstated, and eight new species are described viz. S. austropiceum A.R.Bean, S. elatius A.R.Bean, S. iodinum A.R.Bean, S. kentrocaule A.R.Bean, S. octonum A.R.Bean, S. piceum A.R.Bean, S. pycnotrichum A.R.Bean and S. reclusum A.R.Bean. A lectotype is chosen for S. morrisonii. Descriptions, illustrations and distribution maps are provided for all species.
A re-assessment of the varieties recognised in Verticordia plumosa (Myrtaceae: Chamelaucieae)
HARRIS, A.M. AND RYE, B.L., Nuytsia23: 163–170 (2013)
The seven varieties of Verticordia plumosa (Desf.) Druce are re-assessed in the light of recent collections. Verticordia plumosa var. pleiobotrya A.S.George is reduced to a synonym of V. plumosa var. brachyphylla (Diels) A.S.George. A key and distribution maps are provided for the six remaining varieties, two of which have conservation priority.
Removal of Gunniopsis sp. Fortescue (M.E. Trudgen 11019) from Western Australia’s plant census
Lepidosperma apricola R.L.Barrett is a new species from the Darling Range in Western Australia. An isolated population also occurs in Kings Park, in the heart of Perth. This species has been confused with L. leptostachyum Nees. in the past. Lepidosperma calcicola R.L.Barrett & K.L.Wilson is a new species from coastal dune systems on the west coast of Western Australia, which has been previously confused with a number of other taxa. It has been listed on FloraBase as Lepidosperma sp. Coastal Dunes (R.J. Cranfield 9963). Both are common species occurring in the Perth region of Western Australia (and more broadly in the South West Botanical Province) that have been unnamed up until now.
A revision of the south-western Australian genus Astartea (Myrtaceae: Chamelaucieae)
Astartea DC. is a long-established, taxonomically difficult genus closely related to Cyathostemon Turcz. and Hypocalymma (Endl.) Endl. It is restricted to damp habitats of the South West Botanical Province of Western Australia. In this revision of the genus, 22 species are recognised, including 11 new species (A. cicatricosa Rye & Trudgen, A. decemcostata Rye, A. eobalta Rye, A. graniticola Rye & Trudgen, A. middletonii Rye, A. montana Rye, A. onycis Rye & Trudgen, A. schaueri Rye & Trudgen, A. reticulata Rye, A. transversa Rye and A. zephyra Rye & Trudgen) and one new subspecies (A. aspera Schauer subsp. riparia Rye). A presumed hybrid between A. arbuscula (R.Br. ex Benth.) Rye and A. corniculata Schauer is also described. Distinguishing characteristics, insect associations and other aspects of the biology of Astartea are discussed and illustrated.
Two new species of Westringia sect. Cephalowestringia (Lamiaceae: Westringieae) from the south-west of Western Australia
DAVIS, R.W. AND JOBSON, P., Nuytsia23: 271–276 (2013)
Westringia fitzgeraldensis R.W.Davis & P.Jobson and W. ophioglossa R.W.Davis & P.Jobson are described here as new. A modification to the existing key for Westringia Sm. sect. Cephalowestringia Kuntze is provided to account for W. fitzgeraldensis and W. ophioglossa. Westringia fitzgeraldensis occurs in open mallee in the Fitzgerald River National Park and W. ophioglossa in mallee woodlands in the northern wheatbelt. A distribution map is provided.
Volume 23, 25 July 2013
Acacia gibsonii, a distinctive, rare new species of Acacia sect. Juliflorae (Fabaceae: Mimosoideae) from south-west Western Australia
Acacia gibsonii Maslin, a new species with distinctively short, 3-nerved phyllodes and short spikes, and having affinities to A. incongesta R.S.Cowan & Maslin is described. The species is known from a geographically very restricted area of greenstone hills between Norseman and Hyden. It is currently listed by its phrase name, Acacia sp. Lake Johnson (N. Gibson & M. Lyons 1959), as Priority One under the Department of Environment and Conservation’s Conservation Codes for Western Australian Flora.
A revision of the species of Hypocalymma (Myrtaceae: Chamelaucieae) with smooth or colliculate seeds
RYE, B.L.,WILSON, PAUL G. AND KEIGHERY, G.J., Nuytsia23: 283–312 (2013)
Most members of the south-western Australian genus Hypocalymma (Endl.) Endl. have seeds with a shallowly to very deeply pitted testa. Two small groups of species, both revised here, differ in having a smooth or colliculate testa. Both groups occur in humid environments in the extreme south-west of Western Australia and show vegetative adaptations consistent with this habitat preference. The larger group, Hypocalymma sect. Cardiomyrtus Schauer, is reinstated. A new combination, H. minus (Strid & Keighery) Keighery, is made, bringing the total species recognised to five, and lectotypes are selected for two synonyms, H. boroniaceum F.Muell. ex Benth. and H. hypericifolium Benth. The other group is extremely rare, consisting of the possibly extinct species H. connatum Strid & Keighery, and a new species known from a single population, H. verticillare Rye. The latter group, named here as Hypocalymma sect. Verticilla Rye, is readily disitinguished by its 3-ridged young stems and consistently whorled leaves, and the new species is unusual in having extreme differences in the sizes of the anthers on different stamens within each flower. Molecular data indicate that sect. Verticilla is sister to sect. Cardiomyrtus. Evidence of taxonomic relationships is also presented from studies of hybridisation and insect associations.
A taxonomic update of Conostephium (Ericaceae: Styphelioideae: Styphelieae)
Four new species from the Western Australian endemic genus Conostephium Benth., C. hortiorum Hislop, C. laeve Hislop, C. papillosum Hislop and C. prolatum Hislop are described, illustrated and their distributions mapped. Among these, C. prolatum has a very restricted distribution and is a conservation priority. A key to the 11 recognised species is provided as well as one to distinguish between the two putative generic taxa in the Conostephium clade. Lectotypes are designated for C. pendulum Benth., C. preissii Sond. and for the genus Conostephiopsis Stschegl. Taxonomic notes pertaining to C. drummondii (Stschegl.) C.A.Gardner, C. pendulum, C. preissii and C. roei Benth. are also included.
The Wollastonia/Melanthera/Wedelia generic complex (Asteraceae: Ecliptinae), with particular reference to Australia and Malesia
The generic limits of Wedelia Jacq., Melanthera Rohr, and Wollastonia DC. ex Decne., as currently recognised, are re-examined on the basis of comparative morphology, and a new classification recognising the first two genera in a restricted sense is proposed, with other taxa redistributed through nine genera. In this classification, Wedelia (including Aspilia Thouars) with c. 100 species, is restricted to the Americas and Africa. Melanthera is restricted to c. five species of the Caribbean basin and northern Andes. It is proposed that African species formerly in Melanthera be transferred to Lipotriche R.Br. and the following new combinations are made: L. scandens (Schum. & Thonn.) Orchard; L. scandens subsp. subsimplicifolia (Wild) Orchard; L. scandens subsp. dregei (DC.) Orchard; L. triternata (Klatt) Orchard; L. abyssinica (Sch.Bip. ex Rich.) Orchard; L. gambica (Hutch. & Dalziel) Orchard; L. pungens (Oliver & Hiern.) Orchard. The autonym L. scandens subsp. scandens is newly created. Echinocephalum Gardner of South America is resurrected, with a single species (E. latifolium Gardner). It is proposed that Wollastonia be retained as a genus distinct from Wedelia, Melanthera and Lipochaeta DC., with which it has been variously synonymised by recent authors. In Australia two species of Wollastonia are recognised, W. biflora (L.) DC. and W. uniflora (Willd.) Orchard. These species are keyed, described and illustrated. The Hawai‘ian species of Lipochaeta sect. Aphanopappus (Endl.) Benth. & Hook.f. are transferred to Wollastonia, and placement of Wollastonia lifuana (Hochr.) Fosb. of New Caledonia and Vanuatu, and the Asian species Wedelia prostrata Hemsl. in Wollastonia (as Wollastonia dentata) is confirmed. New combinations are made for Wollastonia biflora var. ryukyuensis (H.Koyama) Orchard, W. bryanii (Sherff) Orchard, W. dentata (H.Lév. & Vaniot) Orchard, W. fauriei (H.Lév.) Orchard, W. integrifolia (Nutt.) Orchard, W. kamolensis (O.Deg. & Sherff) Orchard, W. lavarum (Gaudich.) Orchard, W. micrantha (Nutt.) Orchard, W. micrantha subsp. exigua (O.Deg. & Sherff) Orchard, W. perdita (Sherff) Orchard, W. populifolia (Sherff) Orchard, W. remyi (A.Gray) Orchard, W. subcordata (A.Gray) Orchard, W. tenuifolia (A.Gray) Orchard, W. tenuis (O.Deg. & Sherff) Orchard, W. venosa (Sherff) Orchard, W. waimeaensis (H.St.John) Orchard and W. uniflora (Willd.) Orchard. The autonym W. micrantha subsp. micrantha is newly created. Lipochaeta DC. in Hawai‘i is restricted to the species with 4-lobed disc floret corollas, formerly treated as Lipochaeta sect. Lipochaeta. The Australian and New Guinean species formerly placed in Wedelia are transferred to two new genera: Apowollastonia Orchard, with eight species, including four new combinations (A. longipes (Klatt) Orchard, A. spilanthoides (F.Muell.) Orchard, A. stirlingii (Tate) Orchard and A. verbesinoides (Benth.) Orchard) and five new taxa (A. cylindrica Orchard, A. hamersleyensis Orchard, A. hibernica Orchard, A. major Orchard and A. stirlingii subsp. fontaliciana Orchard). The autonym A. stirlingii subsp. stirlingii is newly created, as is the genus Acunniana Orchard, with one species (A. procumbens (DC.) Orchard). In Malesia/Asia, two monotypic new genera are proposed, Indocypraea Orchard (with a single species, I. montana (Blume) Orchard, formerly Wedelia (Wollastonia) montana), and Quadribractea Orchard (with a single species, Q. moluccana (Blume) Orchard, formerly Wedelia moluccana). Five species related to the former Wedelia urticifolia (Blume) DC. are transferred to the new genus Lipoblepharis Orchard (L. urticifolia (Blume) Orchard, with two subspecies L. urticifolia subsp. urticifolia and subsp. hortorum Orchard, L. thailandica (Koyama) Orchard, L. asperrima (Decne.) Orchard, L. stenophylla (Merr.) Orchard and L. floribunda Orchard). Lectotypes are chosen for Verbesina urticifolia Blume, V. moluccana Blume, V. montana Blume, Buphthalmum australe Biehler (≡ Buphthalmum helianthoides sensu Forster), Wedelia spilanthoides F.Muell., Wedelia verbesinoides Benth. and Wedelia stirlingii Tate.

Distinguishing characters of Hemigenia rigida, a conservation significant species confused with H. pritzelii (Lamiaceae: Westringieae)
Hemigenia rigida Benth. (sect. Homalochilus Benth.) is a species of high conservation concern from Western Australia’s Avon Wheatbelt known from three collections made 150 and 20 years apart. Hemigenia pritzelii S.Moore (also sect. Homalochilus), a more frequent species from the Jarrah Forest of south-west Western Australia, has been frequently confused with H. rigida and both were previously confused with H. ramosissima Benth. The mis-application of the name H. rigida to the distinct and more abundant species H. pritzelii has hampered recognition of the potentially dire conservation status of H. rigida. To resolve longstanding confusion, distinguishing characters are provided for H. pritzelii and H. rigida along with morphological descriptions, distribution maps and information on ecology. An interim key to the species of sect. Homalochilus is presented for context and to aid identification.
Hibbertia sp. Mt Lesueur (M. Hislop 174) cannot be maintained as distinct from H. crassifolia
Hibbertia sericosepala K.R.Thiele is described as new. Morphologically similar to H. helianthemoides (Turcz.) F.Muell. and H. huegelii (Endl.) F.Muell., H. sericosepala is distinctive in its combination of sepal and leaf indumentum, floral bract shape and anther and carpel number. It is endemic to the south-west of Western Australia.

An update to the taxonomy of some Western Australian genera of Myrtaceae tribe Chamelaucieae. 1. Calytrix
Calytrix watsonii (F.Muell. & Tate) C.A.Gardner is reinstated and four species with conservation priority are described: C. hislopii Rye, C. patrickiae Rye, C. sagei Rye and C. viscida Rye. Keys are given for the species groups that include these taxa. The current study has eliminated about half of the informal names that have been in use for Western Australian members of the genus. Several species complexes that need further study are noted.
Updates to Western Australia’s vascular plant census for 2012
BIGGS, L.J. AND PARKER, C.M., Nuytsia23: 503–526 (2013)
Taxonomic review of the Drosera indica L. (Droseraceae) complex requires the clarification of a number of published names. This paper is focussed on the application of names applying to taxa occurring in Australia. Two lectotypes are chosen and one neotype is designated for names historically listed as synonyms of D. indica. Drosera serpens Planch. and D. angustifolia F.Muell. are lectotypified. A neotype is selected for D. hexagynia Blanco as no original material is known. Drosera hexagynia is considered to be a synonym of D. indica. Drosera angustifolia and D. indica f. robusta F.M.Bailey are here considered to be synonyms of D. finlaysoniana Wall. ex. Arn. Drosera angustifolia var. purpuriflora F.Muell. ex Diels is an illegitimate name. Notes are provided on D. hartmeyerorum Schlauer, the only other named Australian taxon in this species complex. Characteristics of the seeds, anthers and glandular hairs are considered diagnostic at the species level. Illustrations of key identifying features and full descriptions of the Australian species are provided.
A baker’s dozen of new wattles highlights significant Acacia (Fabaceae: Mimosoideae) diversity and endemism in the north-west Kimberley region of Western Australia
MASLIN, B.R.,BARRETT, M.D. AND BARRETT, R.L., Nuytsia23: 543–587 (2013)
Thirteen new species of Acacia Mill. from the Kimberley region in northern Western Australia are described. These species are accommodated into three sections of the genus. Acacia sect. Juliflorae (Benth.) Maiden & Betche: A. anastomosa Maslin, M.D.Barrett & R.L.Barrett, A. camptocarpa Maslin, M.D.Barrett & R.L.Barrett, A. cyclocarpa Maslin, M.D.Barrett & R.L.Barrett, A. diastemata Maslin, M.D.Barrett & R.L.Barrett, A. phacelia Maslin, M.D.Barrett & R.L.Barrett and A. synantha Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Plurinerves (Benth.) Maiden & Betche: A. anserina Maslin, M.D.Barrett & R.L.Barrett, A. obtriangularis Maslin, M.D.Barrett & R.L.Barrett, A. orthotropica Maslin, M.D.Barrett & R.L.Barrett and A. perpusilla Maslin, M.D.Barrett & R.L.Barrett. Acacia sect. Lycopodiifoliae Pedley: A. claviseta Maslin, M.D.Barrett & R.L.Barrett, A. dimorpha Maslin, M.D.Barrett & R.L.Barrett and A. prolata Maslin, M.D.Barrett & R.L.Barrett. Notes are provided on A. gracillima Tindale (Acacia sect. Juliflorae) which provisionally includes a poorly known, distinctive entity in need of further taxonomic scrutiny. Except for A. claviseta, which extends to the Northern Territory, the new species are endemic to the Kimberley region. Eleven of the new species (all except A. camptocarpa and A. claviseta) are endemic to the high-rainfall area of the north-west Kimberley, highlighting significant levels of plant endemism in this region. A number of these species are geographically restricted (three are known only from the type) and all except A. prolata are treated as Priority taxa under the Department of Parks and Wildlife’s Conservation Codes for Western Australian Flora. Most of the new species are killed by fire and their distributions are restricted to rocky, presumably naturally fire-limiting sites.
Amanita lesueurii and A. wadjukiorum (Basidiomycota), two new species from Western Australia, and an expanded description of A. fibrillopes
DAVISON, E.M.,MCGURK, L.E.,BOUGHER, N.L.,SYME, K. AND WATKIN, E.L.J., Nuytsia23: 589–606 (2013)
Three species of Amanita Pers. are documented from Western Australia. Amanita lesueurii E.M.Davison is described from the mid-west region. It is distinguished by its small to medium fruiting bodies with a white pileus and white universal veil (both of which become vinaceous-buff or grey with age), white gills, short white stipe with a small obconic or turbinate bulb, white partial veil, amyloid, elongate to cylindrical spores, and no clamp connections. Amanita wadjukiorum E.M.Davison is described from the Perth metropolitan area. It has medium to large fruiting bodies with a cream pileus that ages milky coffee to snuff brown, a pale grey or buff universal veil that ages hazel to drab, cream gills, grey to buff stipe with a napiform or fusiform bulb, white to cream to vinaceous-buff partial veil that disappears with age, amyloid, ellipsoid to elongate spores and no clamp connections. Amanita fibrillopes O.K.Mill., which was previously only known from the type locality, is a widespread but misidentified species. It has small to large fruiting bodies with a pale peach to pale salmon pileus that rapidly ages cream, a white universal veil that rapidly ages buff or milky coffee, white gills that age buff, white or pale pink stipe with a spherical or obconic or tapered bulb, white or buff apical partial veil that disappears with age, inamyloid, ellipsoid to elongate spores and no clamp connections. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank.
