New species and notes on central Australian Goodenia (Goodeniaceae)
ALBRECHT, D.E., Nuytsia 15 (1): 1–9 (2002)
Goodenia halophila Albr. sp. nov. and G. cylindrocarpa Albr. sp. nov. are described, with notes on their distribution, conservation status, habitat and relationships with other species of Goodenia Sm. Notes are also provided on the Northern Territory populations of G. angustifolia Carolin and G. glandulosa K.Krause, and on all populations of G. anfracta J.M.Black and G. maideniana W.Fitzg. Further studies are needed to establish whether G. anfracta, which currently has conservation priority in Western Australia, should be reduced to synonymy under G. maideniana.
A revision of Byblis (Byblidaceae) in south-western Australia
CONRAN, J.G., Nuytsia 15 (1): 11–19 (2002)
The south-western Australian populations of Byblis (Byblidaceae) are revised. A new species, B. lamellata Conran & Lowrie, is recognised on habit, ecology and seed morphology and named for the populations between Arrowsmith River and Cataby. Byblis gigantea Lindl. and its synonym B. lindleyana Planch. are lectotypified. A generic description and a table of distinguishing features for all species is given. A key and distribution map are provided for the two species from the south-west of Western Australia.
Conostephium magnum (Epacridaceae), a new species from Western Australia
CRANFIELD, R.J., Nuytsia 15 (1): 21–25 (2002)
A new species of Epacridaceae endemic to the South West Botanical Province of Western Australia, Conostephium magnum Cranfield, is described, illustrated and mapped. It is related to C. minus Lindl. and C. pendulum Benth.
A comparison of the leaf anatomy of Ficus subpuberula, F. atricha, and F. brachypoda (Moraceae: Urostigma sect. Malvanthera)
DIXON, D.J., Nuytsia 15 (1): 27–32 (2002)
The leaf anatomy of Ficus subpuberula Corner, F. atricha D.J.Dixon, and F. brachypoda (Miq.) Miq. are compared in order to facilitate identification of these partly sympatric species. Ficus subpuberula was found to possess distinctly thinner (267.6 ± 4.3 µm), isobilateral leaves compared to the much thicker (313.3 ± 12.1 µm and 425.6 ± 17.8 µm), dorsiventral leaves of F. atricha and F. brachypoda respectively. Tanniniferous cells were present in F. atricha and F. brachypoda, but absent in F. subpuberula. The upper epidermis and the palisade parenchyma of F. brachypoda were about twice as thick as in F. atricha.
A new species of Blennospora (Asteraceae: Gnaphalieae) from the Swan and Scott Coastal Plains of Western Australia
KEIGHERY, G.J., Nuytsia 15 (1): 33–36 (2002)
A new species of Blennospora A. Gray, B. doliiformis Keighery, is described from the Swan and Scott Coastal Plains. The species occurs on clay soils in fresh winter-wet sites. A key is given to the three species now recognised in the genus.
A review of the genus Pileanthus (Myrtaceae)
KEIGHERY, G.J., Nuytsia 15 (1): 37–51 (2002)
Pileanthus Labill., a small genus of floriferous shrubs endemic to southern Western Australia, is reviewed. Eight species are recognised, one of which has two subspecies. Four new species (Pileanthus auranticus Keighery, P. bellus Keighery, P. rubronitidus Keighery and P. septentrionalis Keighery) and one new subspecies (P. peduncularis subsp. piliferus Keighery) are described, and P. vernicosus F. Muell. is reinstated.
Two new species of Comesperma (Polygalaceae) from Western Australia
KEIGHERY, G.J., Nuytsia 15 (1): 53–57 (2002)
Two new species of Comesperma Labill. from the south-west of Western Australia, C. calcicola Keighery and C. griffinii Keighery, are described and illustrated. Both species are regarded as poorly collected and in need of further survey to determine their conservation status. The great diversity of life forms found in south-western members of the genus is outlined.
Drosera pedicellaris (Droseraceae), a new species from south-west Western Australia
LOWRIE, A., Nuytsia 15 (1): 59–62 (2002)
A new species, Drosera pedicellaris Lowrie, is described and illustrated. It is related to D. parvula Planchon and is known from only two localities in the south-west of Western Australia.
Eucalyptus calyerup (Myrtaceae), a new species of possible hybrid origin from south-western Australia
MCQUOID, N.K. AND HOPPER, STEPHEN D., Nuytsia 15 (1): 63–68 (2002)
Eucalyptus calyerup McQuoid & Hopper is described and illustrated. It appears to be of possible hybrid origin, but morphologically stable, with the putative parents being Eucalyptus occidentalis Endl. and E. platypus Hook. subsp. platypus. It is endemic to the Calyerup Rocks area near Jerramungup in Western Australia and has aroused much interest from landcare groups. It is rare in the wild and in need of monitoring.
A revision of Eucalyptus series Calcicolae (Myrtaceae) from the south coast of Western Australia
NICOLLE, D., Nuytsia 15 (1): 69–76 (2002)
Eucalyptus series Calcicolae Brooker consists of four closely related taxa, two of which are newly described. E. calcicola Brooker subsp. calcicola is restricted to the Hamelin Bay area on the Leeuwin Coast, and subsp_. unita_ Nicolle subsp. nov. occurs in scattered populations from west of Denmark eastwards towards Bremer Bay. E. ligulata Brooker subsp. ligulata occurs from Cape Le Grand to Cape Arid, and subsp. stirlingica Nicolle subsp. nov. is restricted to the Stirling Range. A key and distribution map for the taxa of Eucalyptus ser. Calcicolae are presented.
Two new species of silver mallet (Eucalyptus - Myrtaceae) of very restricted distribution in south-western Western Australia
NICOLLE, D., Nuytsia 15 (1): 77–83 (2002)
Eucalyptus rugulata Nicolle sp. nov. is described from the South Ironcap-Hatter Hill area north-east of Lake King, distinguished within the silver mallets by its broad and thick adult leaves and the large and robust buds and fruits. E. purpurata Nicolle sp. nov. is described from a single population near Bandalup Hill east of Ravensthorpe. It is distinguished from E. argyphea L.A.S. Johnson & K.D. Hill by the conspicuous red-purple new growth and the smaller buds and fruits. Both new species are of restricted distribution and E. purpurata, in particular, is considered to be at risk. A key and distribution map for the silver mallets are presented.
One new Banksia and two new Grevillea species (Proteaceae: Grevilleoideae) from Western Australia
OLDE, PETER M. AND MARRIOTT, NEIL R., Nuytsia 15 (1): 85–99 (2002)
Banksia rosserae P. Olde & N. Marriott, a new species of Banksia R. Br., Grevillea kirkalocka P. Olde & N. Marriott and G. squiresae P. Olde & N. Marriott, two new species of Grevillea R. Br. (Proteaceae: Grevilleoideae) are described. Their affinities are discussed and keys are provided. All of the new species have conservation priority.
A revision of the south-western Australian species of Micromyrtus (Myrtaceae) with five antisepalous ribs on the hypanthium
RYE, B.L., Nuytsia 15 (1): 101–122 (2002)
Among the species currently included in Micromyrtus Benth., two main categories are distinguished here on the basis of hypanthium ribbing, one characterised by having antipetalous ribs and usually also antisepalous ones, the other by having antisepalous ribs but no antipetalous ones. Most species belong to the latter category, including the lectotype selected here for the genus, Micromyrtus drummondii Benth. nom. superfl. [= M. obovata (Turcz.) J.W. Green]. A key is given to the 14 Western Australian members of this group, and the eight south-western species, including five new species, are revised. Micromyrtus erichsenii Hemsl. is reinstated and the new species M. monotaxis Rye, M. ninghanensis Rye, M. papillosa J.W. Green ex Rye, M. rogeri J.W. Green ex Rye and M. uniovula Rye are illustrated. Three of these new species have an ovule number of one, lower than any previously recorded for the genus, and four of them have conservation priority.
Scaevola ballajupensis (Goodeniaceae), a new species from the Jarrah forest of south-western Australia
SAGE, L.W., Nuytsia 15 (1): 123–126 (2002)
The new species Scaevola ballajupensis L.W. Sage, from the south-western Australian Jarrah forest, is described and photographically illustrated. The species is known only from one locality on private property and therefore has a high conservation priority. An amendment to the key to Scaevola species in "Flora of Australia" is made to include the new taxon and a table showing how it differs from its closest relatives is provided.
A revision of Hibbertia depressa and its allies (Dilleniaceae) from Western Australia
WHEELER, J.R., Nuytsia 15 (1): 127–138 (2002)
A small group of closely related taxa, which form part of section Candollea Gilg. in the genus Hibbertia Andr., are revised. Descriptions, illustrations and distribution maps are presented along with a key, including two new taxa, Hibbertia fitzgeraldensis J.R. Wheeler and Hibbertia priceana J.R. Wheeler. Both new species are restricted in distribution and Hibbertia priceana appears to be at risk. The lectotypification of Hibbertia desmophylla (Benth.) F. Muell. is also made.
Miscellaneous new species of Hibbertia (Dilleniaceae) from the wheatbelt and pastoral regions of Western Australia
WHEELER, J.R., Nuytsia 15 (1): 139–152 (2002)
The new taxa, Hibbertia ancistrophylla J.R. Wheeler, H. ancistrotricha J.R. Wheeler, H. avonensis J.R. Wheeler, H. lepidocalyx J.R. Wheeler, H. lepidocalyx subsp. tuberculata J.R. Wheeler and H. stenophylla J.R. Wheeler are described, mapped and illustrated. All belong to either section Pleurandra (Labill.) Benth. or section Hemipleurandra Benth. They are recorded from the Avon Wheatbelt, Jarrah Forest and Mallee regions of the South West Botanical Province and the Coolgardie, Murchison and Yalgoo regions of the Eremaean Province.
Lectotypification of two Western Australian species of Micromyrtus (Myrtaceae)
RYE, B.L., Nuytsia 15 (1): 153–154 (2002)
Among the species of Micromyrtus Benth. (Myrtaceae) that Bentham (1867) described in "Flora Australiensis", were two Western Australian species that had previously been recognised as distinct taxa by Ferdinand von Mueller. One had been described as Thryptomene elobata (Mueller 1864) and another had been given the manuscript name T. racemosa F. Muell. The purpose of this short communication is to select a lectotype from among the syntypes of each of these species.
