DAVIS, R.W. AND HURTER, P.J.H., Nuytsia 23: 1–4 (2013)
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
BARRETT, R.L., Nuytsia 23: 5–21 (2013)
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 (Ericaceae: Styphelioideae: Styphelieae) from Western Australia
HISLOP, M., WILSON, A.J.G. AND PUENTE-LELIÈVRE, C., Nuytsia 23: 23–42 (2013)
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., Nuytsia 23: 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.

LEWINGTON, M.A., Nuytsia 23: 101 (2013)
Two Western Australian species of Ozothamnus transferred to Pithocarpa (Asteraceae: Gnaphalieae)
BARRETT, R.L., SCHMIDT-LEBUHN, A.N. AND THIELE, K.R., Nuytsia 23: 103–108 (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.

A taxonomic review of the Solanum sturtianum subgroup of subgenus Leptostemonum (Solanaceae)
BEAN, A.R., Nuytsia 23: 129–161 (2013)
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., Nuytsia 23: 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
WEGE, J.A., Nuytsia 23: 171–172 (2013)
Two new species of Lepidosperma (Cyperaceae) occurring in the Perth area of Western Australia
BARRETT, R.L. AND WILSON, K.L., Nuytsia 23: 173–187 (2013)
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)
RYE, B.L., Nuytsia 23: 189–269 (2013)
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., Nuytsia 23: 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.
Acacia gibsonii, a distinctive, rare new species of Acacia sect. Juliflorae (Fabaceae: Mimosoideae) from south-west Western Australia
MASLIN, B.R., Nuytsia 23: 277–281 (2013)
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., Nuytsia 23: 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.
