A new taxon, Eucalyptus conglobata R. Br. ex Maiden subsp. perata Brooker & Slee, from southern Western Australia is described and illustrated. A distribution map for the typical and the new subspecies is provided. A brief discussion of the large E. series Rufispermae to which the species belongs is given.

New species and lectotypifications of some reticulate-nerved Tephrosia (Fabaceae) from north-west Australia and the genus Paratephrosia re-evaluated

COWIE, I.D., Nuytsia 15 (2) : 163–186 (2004)

Eight new species of reticulate-nerved Tephrosia are described from the Kimberley Region of Western Australia and the Northern Territory (T. andrewii Cowie, Tephrosia bifacialis Cowie, T. carriemichelliae Cowie, T. ephippioides Cowie, T. gyropoda Cowie, T. humifusa Cowie, T. procera Cowie, and T. valleculata Cowie). Paratephrosia is reduced to synonymy under Tephrosia and a new name, Tephrosia lasiochlaena Cowie, is published for P. lanata. Lectotypifications are provided for six reticulate-nerved and allied taxa of Tephrosia (T. flammea F. Muell. ex Benth., T. nematophylla F. Muell., T. oblonga R. Br. ex Benth., T. polyzyga F. Muell. ex Benth., T. porrecta R. Br. ex Benth. and T. reticulata R. Br. ex Benth.).

A list of known lichen taxa for Western Australia is presented; family, genus, species and infra species are listed with authors and reference to original publication. Biogeographic regions are indicated for each species based on the collections of the Western Australian Herbarium. A table giving statistical data for families and genera is included.

Two new species of Ptilotus (Amaranthaceae) from Western Australia

DAVIS, R.W., Nuytsia 15 (2) : 221–226 (2004)

Two new species of Ptilotus (Amaranthaceae) from the central and southern regions of Western Australia are described: Ptilotus chrysocomus R.W. Davis, known from one location near the Carnarvon Range in the vicinity of the abandoned Blue Hill Station, Little Sandy Desert; and Ptilotus halophilus R.W. Davis, known from the margins of Lake Altham and from Lake Hurlstone Reserve in the Lake Grace to Pingrup and Holt Rock to Hyden areas.

Eucalyptus virginea and E. relicta (Myrtaceae), two new rare forest trees from south-western Australia allied to E. lane-poolei, and a new phantom hybrid

HOPPER, S.D. AND WARDELL-JOHNSON, G., Nuytsia 15 (2) : 227–240 (2004)

Eucalyptus virginea and E. relicta are described from Mt Lindesay National Park and from the Whicher Range south-east of Busselton respectively. Both species, together with E. lane-poolei, are in the earliest branching clade of E. ser. Curviptera, which contains many horticulturally attractive large-flowered mallees from semi-arid and desert regions such as E. macrocarpa and E. youngiana. The discovery and description of these two rare relictual forest trees so recently highlights the need for ongoing botanical survey of south-western Australia’s forests. A phantom hybrid, Eucalyptus lane-poolei × relicta, is also described for the first time. It occurs close to populations of E. relicta in the Whicher Range but 150 km south of the nearest recorded E. lane-poolei.

A new species of Bulbine (Asphodelaceae) from Western Australia

KEIGHERY, G.J., Nuytsia 15 (2) : 241–244 (2004)

A new species of Bulbine Wolf, B. pendula Keighery, is described and illustrated. The species is confined to cracking clay wetlands in the Pilbara, Carnarvon, Ashburton and Great Sandy Desert Biogeographical Regions of arid Western Australia.

A taxonomic review of the genus Agrostocrinum (Phormiaceae)

KEIGHERY, G.J., Nuytsia 15 (2) : 245–252 (2004)

The genus Agrostocrinum F. Muell. is reviewed. Two species are recognised, A. hirsutum (Lindl.) Keighery and A. scabrum (R. Br.) Baillon, both confined to southern Western Australia. A distinctive inbreeding maritime race of the latter, found in scattered populations on granites along the south coast, is described as a new subspecies, A. scabrum subsp. littorale Keighery.

Taxonomic notes on the Angianthus drummondii complex (Asteraceae : Gnaphaliinae)

KEIGHERY, G.J., Nuytsia 15 (2) : 253–260 (2004)

Angianthus drummondii is revised and shown to be a species complex of three allopatric species. The complex comprises A. drummondii (Turcz.) Benth., an erect plant with long inflorescence bracts confined to fresh water clay-based wetlands; A. platycephalus Benth., a prostrate plant with short broad inflorescence bracts, growing in fresh to brackish clay soils, is resurrected; and a new species A. halophilus Keighery, an erect plant with short inflorescence bracts, found on gypsum soils, is described.

Taxonomy of the Calytrix ecalycata complex (Myrtaceae)

KEIGHERY, G.J., Nuytsia 15 (2) : 261–268 (2004)

The part of the genus Calytrix Labill. that was formerly regarded as the monotypic genus Calythropsis C.A. Gardner is shown to be composed of two allopatric species, Calytrix ecalycata Craven and C. pimeleoides C.A. Gardner ex Keighery. The former species is comprised of three geographically separated subspecies, C. ecalycata subsp. ecalycata, C. ecalycata subsp. brevis Keighery and C. ecalycata subsp. pubescens Keighery.

A review of Hibbertia hemignosta and its allies (Dilleniaceae) from Western Australia

WHEELER, J.R., Nuytsia 15 (2) : 277–298 (2004)

The group of species that includes Hibbertia hemignosta (Steud.) J.R. Wheeler is reviewed and a key provided. The new species Hibbertia acrotrichion J.R. Wheeler and Hibbertia chartacea are described. Two new varieties of Hibbertia hibbertioides (Steud.) J.R. Wheeler, var. meridionalis and var. pedunculata, and two new varieties of Hibbertia pulchra Ostenf., var. acutibractea and var. crassinervia, are also described. All taxa are mapped and illustrated. Both new species have conservation priority, but the four new varieties are not considered endangered.

Miscellaneous new Hibbertia species (Dilleniaceae) from the south coast and adjacent interior of Western Australia

WHEELER, J.R., Nuytsia 15 (2) : 299–310 (2004)

Five new species of Hibbertia Andr. are formally described. Hibbertia oligantha J.R. Wheeler, Hibbertia pachyphylla J.R. Wheeler, Hibbertia papillata J.R. Wheeler, Hibbertia psilocarpa J.R. Wheeler and Hibbertia turleyana J.R. Wheeler all from the south coast area of the South-West Botanical Province (Esperance Plains region and Mallee region) with two species extending to the southern Eremaean Province (Coolgardie region). All species are mapped and the three having conservation priority are illustrated.

An interim key to the Western Australian species of Hibbertia (Dilleniaceae)

A key is presented to the Western Australian species of Hibbertia following the formal recognition of numerous new species in recent years.

Recognition of Eucalyptus quaerenda at specific rank

BYRNE, M., Nuytsia 15 (2) : 321–323 (2004)

Phylogenetic analysis of the relationships between the taxa in the Eucalyptus angustissima complex have been investigated using RFLP analysis of nuclear genome (Elliott and Byrne 2003) (Voucher specimens at PERTH: W. O’Sullivan 127, 357, 812, 968, 966, 1183, 1190, 1193, 1194). This study assessed populations of E. angustissima subsp. angustissima, E. angustissima subsp. quaerenda, E. foliosa and E. misella and found all four taxa to be genetically distinct. Eucalyptus angustissima was not monophyletic as the two subspecies did not cluster together. Eucalyptus misella was sister species to E. angustissima subsp. angustissima, and E. foliosa was sister species to both these taxa. Eucalyptus angustissima subsp. quaerenda was the most distinct of the four taxa.

Correction of type locality and flowering time for Melaleuca apostiba (Myrtaceae)

LEWINGTON, M., Nuytsia 15 (2) : 324–324 (2004)

Melaleuca apostiba K.J. Cowley was described from a specimen collected by R. Morland during a Lands & Surveys Department expedition to the Officer Basin in 1963. The holotype of M. apostiba has the collecting number M10, with the label recording the locality as ‘between Carnegie and Giles’ and the collection date as June 1963.

A first report of Leptochloa panicea subsp. brachiata (Poaceae) from Western Australia

SNOW, NEIL, Nuytsia 15 (2) : 325–326 (2004)

The genus Leptochloa P. Beauv. (Poaceae) is represented by nine species in Australia (Sharp and Simon 2002). Three of these include subspecies, bringing the total number of taxa in Australia to fourteen. I report here the first confirmed occurrence in Western Australia of Leptochloa panicea (Retz.) Ohwi subsp. brachiata (Steud.) N. Snow, a non-native taxon of neotropical origin.

Nomenclatural notes on two species of Hibbertia (Dilleniaceae)

WHEELER, J.R., Nuytsia 15 (2) : 327–328 (2004)

Examination of type material of Hibbertia rhadinopoda and closely related taxa has revealed that there is an earlier name for H. rhadinopoda in the genus Pleurandra Labill. The necessary new combination is made here. A lectotype is also chosen for Hibbertia inclusa.
