Three new series, six new subseries, twenty-two new species and twenty new subspecies of Eucalyptus are described. New taxa are treated in the order and nomenclature of the Flora of Australia Volume 19 (1988) from which we deviate only when we consider an updated treatment necessary. The new series Falcatae is erected and divided into two subseries, Falcatae and Decipientes. The series Micrantherae s.s. is expanded to include the new subseries Bakerianae, and a new series Balladonienses is erected. E. lane-poolei of series Curviptera is segregated in the new E. subseries Inflexae, E. caesia in the new E. series Caesiae, while E. series Orbifoliae comprises the remaining Minni Ritchi species. A new subseries Cupreanae is erected in E. series Lucasianae. Diagnostic notes on each taxonomic series are given at the head of the relevant groups of species throughout the paper. The new taxa are illustrated, except for E. ebbanoensis subsp. photina and E. marginata subsp. thalassica for which leaf colour and leaf gloss are the diagnostic characters, E. marginata subsp. elegantella and E. macrocarpa subsp. elachantha for which habit, bark characters and leaf, bud and fruit dimensions are the diagnostic characters and E. decipiens subspp. chalara and adesmophloia for which bark characters only are diagnostic. Distribution maps are provided. All the new taxa are endemic to Western Australia except for E. glomerosa and E. kingsmillii subsp. alatissima, both of which extend into the desert region of South Australia.
Acacia Miscellany 7. Acacia sulcata and related taxa (Leguminosae : Mimosoideae) in Western Australia
COWAN, R.S. AND MASLIN, B.R., Nuytsia9 (1): 69–78 (1993)
A key is presented to the nine taxa of the informal “A. sulcata group”, followed by a review of A. sulcata R. Br., including the description of a new variety A. sulcata var. planoconvexa Cowan & Maslin; in addition, a new variety of A. brachyphylla Benth. is described (var. recurvata Cowan & Maslin) and a new species, A. octonervia Cowan & Maslin. In addition, A. nitidula Benth. and A. sulcata var. platyphylla have been lectotypified.
Acacia Miscellany 8. Acacia masliniana (Leguminosae : Mimosoideae : section Plurinerves), a new species of Western Australia
Acacia coriacea DC. is regarded as comprising three subspecies, subsp. coriacea (which is here lectotypified), subsp. pendens Cowan & Maslin, subsp. nov. and subsp. sericophylla (F. Muell.) Cowan & Maslin, comb. et stat. nov. These are described and compared with the similar appearing A. stenophylla; a key is provided to distinguish the four taxa.
A new species of Restionaceae from south-western Australia
Restio isomorphus is a new species of Australian Restionaceae from a restricted area in the south-west of Western Australia. Rhizome morphology and ecological factors likely to influence the conservation status of this species are discussed.
Drummondita wilsonii, Philotheca langei and P. basistyla (Rutaceae), new species from south-west Western Australia
One new species of Drummondita and two new species of Philotheca are described. All three taxa are apparently rare, each restricted to limited geographic areas. _Drummondita wilsonii_is similar to D. ericoides, but has unequal calyx segments in common with D. miniata. Philotheca langei and P. basistyla both have affinities with Eriostemon falcatus which is currently presumed extinct. Similarities between D. wilsonii, D. ericoides and D. miniata, pollination mechanisms and flower colour variation in Drummondita, distribution and flowering time of the D. ericoides group (which includes D. miniata and D. wilsonii) and the evolutionary history of the Drummondita ericoides group, D. hassellii group and D. calida are discussed.
The status, ecology and relationships of Meziella (Haloragaceae)
ORCHARD, A.E. AND KEIGHERY, G.J., Nuytsia9 (1): 111–117 (1993)
The monotypic genus Meziella has until now been known only from its very fragmentary and immature type. Because of this its status as a genus and relationships have been unclear, and its description has been incomplete. Recent rediscovery of the species has allowed a full description to be prepared for the first time. It is now confirmed that Meziella is a distinct genus, intermediate in many respects between Haloragis and Myriophyllum. Its somewhat bizarre features are described, its ecology discussed, and a revised key to the Australian genera of the family is provided.
Thomasia glabripetala (Sterculiaceae), a new species from south-west Western Australia
A new species of Thomasia (Sterculiaceae) is described and illustrated, namely Thomasia glabripetala S.J. Patrick, endemic to the Avon Botanical District of the South-West Botanical Province of Western Australia. This is a declared rare species which, until recently, has been confused with Thomasia montana Steudel.
Croninia kingiana (Epacridaceae), a change in status for Leucopogon kingianus
Leucopogon kingianus, an endemic Western Australian species exhibiting features atypical of Leucopogon is transferred to the new monotypic genus Croninia J. Powell as C. kingiana (F. Muell.) J. Powell.
Cytological notes in Rutaceae. 1 Boronia tenuis
STACE, HELEN M. AND PATRICK, S.J., Nuytsia9 (1): 131–133 (1993)
Eremaea is a genus of shrubs and small trees endemic in south-western Australia. It has an unusual distribution in that 15 of its 16 species occur on or very close to the coastal plain (Irwin and Darling Botanical Districts) and one species extends throughout much of the non-forested areas of the South West Botanical Province. The genus is a significant component of the shrub layer of several vegetation types. Eight new species, 5 subspecies, and 8 varieties are described (E. asterocarpa subsp. asterocarpa, E. asterocarpa subsp. histoclada, E. asterocarpa subsp. brachyclada, E. atala, E. hadra, E. beaufortioides var. beaufortioides, E. beaufortioides var. lachnosanthe, E. beaufortioides var. microphylla, E. blackwelliana, E. ebracteata var. ebracteata, E. ebracteata var. brachyphylla, E. x codonocarpa, E. dendroidea, E. ectadioclada, E. pauciflora var. pauciflora, E. pauciflora var. calyptra, E. pauciflora var. lonchophylla, E. x phoenicea, E. violacea subsp. violacea and E. violacea subsp. raphiophylla). Keys to and descriptions of taxa, and illustrations of most taxa are presented. An index to taxa is given on page 222.
Nemcia effusa (Fabaceae : Mirbelieae), a new species from south-west Western Australia, and a key to Nemcia
CRISP, M.D. AND MOLLEMANS, F.H., Nuytsia9 (2): 223–232 (1993)
A new species of Nemcia, N. effusa Crisp & Mollemans, is described from the north-west part of Lake Grace shire, south-west Western Australia. The species is quite distinct with no clear affinities. It is named for its habit with rigid, diffuse stems and branchlets. In some respects similar to N. stipularis (Meissner) Crisp, it differs in the leaves spreading widely and being broader(3-4 mm) and impressed-punctate below, and with stipules shorter (2-3 mm). It is also similar to N. punctata (Turcz.) Crisp in the leaves being impressed-punctate below, but differing in having conspicuous stipules and longer leaves (1-2.5 cm) that are spreading widely but scarcely recurved. Only two plants of N. effusa were found at the type locality, and the species was not observed elsewhere during surveys of remnant vegetation (by the second author) of c. 71,250 km² of the southern wheatbelt region of Western Australia. This suggests that N. effusa is neither widespread nor common.
Wurmbea calcicola (Colchicaceae), a new species from Cape Naturaliste, south western Australia
Eight new species and 8 new subspecies are described; 3 currently accepted subspecies are raised to specific rank; 1 species currently in synonymy is reinstated at specific rank. Keys are provided to enable separation from closely related species. An index to taxa is given on page 304.
Eucalyptus series Brevifoliae (Myrtaceae), a new series of northern Australian eucalypts
BROOKER, M.I.H. AND SLEE, A.V., Nuytsia9 (3): 307–314 (1994)
A new infrageneric taxon, Eucalyptus series Brevifoliae is described. The group consists of six species of northern Australian white gums, viz.E. confluens, E. rupestris and E. ordiana, endemic to the Kimberley in Western Australia, E. brevifolia, from the Kimberley and adjacent parts of the Northern Territory, E. umbrawarrensis endemic to the Top End of the Northern Territory, and E. leucophloia which occurs from the Pilbara across the Northern Territory to western Queensland. The series is diagnosed by seed and leaf characters.
Mueller’s ‘The plants indigenous to the colony Victoria’ – Is volume 2 effectively published?
Historical notes are provided to support the conclusion that the second volume of this work was not effectively published and the new names it included are therefore invalid. A summary is appended that will be of assistance to librarians and bibliographers in understanding the chronology and content of the several publications concerned.
Three new species, a new name and notes on Australian Polycarpaea (Caryophyllaceae)
Polycarpaea incana,P. microceps and P. tenax are described and illustrated and a new name, P. multicaulis, is chosen for the later homonym P. microphylla Pedley. Variation in these taxa, as well as P. breviflora, P. corymbosa, P. involucrata, P. spirostylis and P. violacea is discussed. A key to Australian species is included.
New taxa of Verticordia (Myrtaceae : Chamelaucieae) from Western Australia
GEORGE, E.A. AND GEORGE, A.S., Nuytsia9 (3): 333–341 (1994)
A new species of Stylidium (Stylidiaceae) from the Kimberley Region, S. costulatum Lowrie and Kenneally is described and illustrated and S. floodii, its closest relative, is lectotypified. The terms cunabulum (for the dilated part of the column) and torosus (for the mobile column hinge) are proposed.
Notes and new species of Acacia (Mimosaceae) from northern Australia
Acacia tolmerensis G. Leach is described as a new species in the informal A. platycarpa group (Sect. Plurinerves). The informal A. plectocarpa group (Sect. Juliflorae) is defined as including A. plectocarpa Cunn. ex Benth. subsp. plectocarpa, A. plectocarpa subsp. tanumbirinensis (Maiden) Pedley, A. armitii F. Muell. ex Maiden and a new species, A. echinuliflora G. Leach. Relationships within the group are discussed, descriptions and a key to all taxa in the group are provided. Distribution maps for all taxa are presented.
Drosera ordensis (Droseraceae), a new tropical species of carnivorous plant from northern Australia
A new species, Drosera ordensis (Droseraceae) is described from tropical northern Australia. The features that distinguish this taxon from its nearest relatives are presented and an indication is given of its habitat preferences.
Stylidium pulviniforme (Stylidiaceae), a new species of triggerplant from south-west Western Australia
LOWRIE, A. AND KENNEALLY, K.F., Nuytsia9 (3): 369–373 (1994)
The new species is described and illustrated with photographs. Chamaexeros longicaulis is most closely related to C. serra but differs in several characteristics including three unique in the genus: elongated stems, elongated rhizomes resulting in vegetative reproduction, and thickened vertical rhizomes which presumably provide for storage of reserves. The species is of conservation interest owing to the small number of populations known, and is listed among conservation priority taxa for Western Australia. A revised key to the species of Chamaexeros is presented. Features of the ovary, capsule and seed are clarified for this genus. Floral measurement data are given for all species. A range extension is noted for C. serra.
C.R.P. Andrews’ species of Acacia (Leguminosae : Mimosoideae) : typification of the names
MASLIN, B.R. AND COWAN, R.S., Nuytsia9 (3): 383–385 (1994)
William Vincent Fitzgerald described 33 new species of Acacia in four papers published between 1904 and 1917. Notes on these publications and on the specimens used by Fitzgerald are provided. Lectotypes are selected for 23 names, based on specimens located at BM (4), PERTH (6) and NSW (13).
C.F. Meissner’s species of Acacia (Leguminosae : Mimosoideae) : typification of names
MASLIN, B.R. AND COWAN, R.S., Nuytsia9 (3): 399–414 (1994)
The type status of names for all 56 taxa described by Meissner in Lehmann’s "Plantae Preissianae" (1844 and 1848) and in a subsequent paper in "Botanisches Zeitung" (1855) has been carefully assessed. Consequently, we have fixed the application of these names by choosing lectotypes wherever possible from among the syntypes, particularly those at BM, LD and NY. Of the lectotypes selected here 19 are at LD, 10 are at NY and 2 at BM.
A contribution to the taxonomy of the Tiliaceae of Western Australia
Nicotiana heterantha Symon & Kenneally is described from near Broome, Western Australia. The new species is known from only two populations, both of which are under threat from grazing. It appears most closely related to N. rosulata subsp. rosulata.
New species of Hibbertia (Dilleniaceae) from the northern wheatbelt area of Western Australia
H. lividula, H. glabriuscula, H. graniticola and H. arcuata from the northern wheatbelt area of Western Australia are described and illustrated. The placement of H. lividula in section Hibbertia subsection Bracteatae and H. glabriuscula in section Hibbertia subsection Ochrolasiae is discussed. The relationship between H. graniticola and H. arcuata is also examined.
