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.
Dipteracanthus chichesterensis (Acanthaceae: Ruellieae), a new geographically and edaphically restricted species from the Pilbara bioregion of Western Australia
TRUDGEN, MALCOLM E. AND DE KOCK, P.-L., Nuytsia25: 161–170 (2015)
Dipteracanthus chichesterensis Trudgen & de Kock is described as a new species of Acanthaceae (tribe Ruellieae Dumort.) restricted to the Chichester Plateau in the Pilbara bioregion of Western Australia. The new species is known from five localities and is considered poorly known and of conservation significance. It is most closely related to D. australasicus F.Muell., differing in stem and leaf indumentum, pollen ornamentation and seed characteristics. A distribution map, photographs and a key to Dipteracanthus Nees taxa currently recognised in Western Australia are provided.
A revision of species from the tribe Lasiopetaleae (Byttnerioideae: Malvaceae) with rostrate anthers
SHEPHERD, K.A. AND WILKINS, C.F., Nuytsia25: 171–189 (2015)
An informal group of species within the tribe Lasiopetaleae Gay, characterised by a lack of stipules and distinctive, rostrate anthers, are revised and included in Lasiopetalum Sm. Revised descriptions are provided for the reinstated L. laxiflorum (Benth.) F.Muell. and newly elevated subspecies of L. glutinosum (Lindl.) F.Muell. (L. glutinosum subsp. glutinosum and L. glutinosum subsp. latifolium (Benth.) K.A.Sheph. & C.F.Wilkins). Three new species of conservation concern are recognised (L. cenobium K.A.Sheph. & C.F.Wilkins, L. trichantherum K.A.Sheph. & C.F.Wilkins and L. venustum K.A.Sheph. & C.F.Wilkins). A distribution map, images and a key to the group are included.
