The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. Please reach out to us if you have any questions or concerns.
The notice period
started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Monday, 2 March 2026 +08:00.
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.
