The Western Australian Herbarium’s collections management system and census were set to read-only mode on 1 October 2025. Taxonomic updates published since this time are not being reflected in Florabase, herbarium collections, or Western Australia’s taxonomic names census (Nomos). Conservation listings displayed on Florabase may also be out of date. Please refer to DBCA’s Threatened species and communities webpage for the most recent Threatened and Priority Flora List, noting that recent taxonomic updates are similarly not included. Our database migration is moving to a staging phase. We thank you for your patience as we ensure the integrity of our biodiversity data, develop new workflows, and train staff to use the new systems. Please reach out to us if you have any questions or concerns.

The notice period started at 12:00 pm on Wednesday, 1 October 2025 +08:00 and will end at 12:00 pm on Friday, 1 January 2027 +08:00.

Distinguishing characters of Hemigenia rigida, a conservation significant species confused with H. pritzelii (Lamiaceae: Westringieae)

GUERIN, G.R., Nuytsia 23: 467–474 (2013)

Details PDF
Hemigenia rigida Benth. (sect. Homalochilus Benth.) is a species of high conservation concern from Western Australia’s Avon Wheatbelt known from three collections made 150 and 20 years apart. Hemigenia pritzelii S.Moore (also sect. Homalochilus), a more frequent species from the Jarrah Forest of south-west Western Australia, has been frequently confused with H. rigida and both were previously confused with H. ramosissima Benth. The mis-application of the name H. rigida to the distinct and more abundant species H. pritzelii has hampered recognition of the potentially dire conservation status of H. rigida. To resolve longstanding confusion, distinguishing characters are provided for H. pritzelii and H. rigida along with morphological descriptions, distribution maps and information on ecology. An interim key to the species of sect. Homalochilus is presented for context and to aid identification.
