Service Notice

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.

Sida picklesiana (Malvaceae), a new species from the Murchison-Gascoyne region of Western Australia
MARKEY, A.S., DILLON, S.J., COCKERTON, G.T.B. AND BARKER, R.M.

This article provides a description of the recently discovered species Sida picklesiana A.S. Markey, S.J. Dillon & R.M. Barker. This species is known from an area near Wiluna in Western Australia’s Murchison-Gascoyne region, where it occurs in a variety of habitats. Sida picklesiana has conservation priority status as it has a relatively limited distribution. Major differences between Sida picklesiana and the species with which it is most likely to be confused are discussed, and the most recently published draft key to Sida is amended to include this new species.
