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.
