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 substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 May 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 Saturday, 2 May 2026 +08:00.

Nuytsia
The journal of the Western Australian Herbarium

Nuytsia is an open access, peer-reviewed journal that publishes original papers on the systematics, taxonomy and nomenclature of Australian (particularly Western Australian) plants, algae and fungi, especially descriptions of taxa, revisions, identification guides, nomenclatural and taxonomic issues, systematic analyses and classifications, censuses, and information on invasive species.

Nuytsia was founded in 1970 and is named after Nuytsia floribunda (Christmas Tree; Moodjar; Kaanya Tree), an arborescent root hemiparasite endemic to south-west Western Australia that is of cultural significance to Noongar Aborigines. One-fifth of all published native plant names for Western Australia have been formally established in the journal, including over one-quarter of the conservation-listed taxa in the State. Refer to the cumulative index to scientific names published in Nuytsia for details, and to the 50th anniversary edition for a synopsis of the journal’s impact.

Nuytsia moved to a hybrid print/online publication model in 2013 and became an online-only publication in 2024. Papers are published electronically on Florabase by the Western Australian Herbarium and are freely available for download and distribution for bona fide scientific or educational use. The journal is also electronically available via the Biodiversity Heritage Library and DBCA library, and is also archived with the National edeposit database. Written permission to use and/or re-publish images and botanical illustrations must be obtained from the Managing Editor. A hard copy of each volume is no longer produced, and subscriptions no longer taken.

Opinions expressed by authors in articles published in Nuytsia are their own and do not necessarily represent the policies or views of the Department of Biodiversity, Conservation and Attractions.

A taxonomic review of the Styphelia blepharolepis group (Ericaceae: Epacridoideae: Styphelieae)

HISLOP, M., Nuytsia 37: 1–16 (2026)

Details PDF
The taxonomy of the small, infrageneric Styphelia blepharolepis group is updated with the addition of two new species, S. cranfieldii Hislop and S. semitrullata Hislop & E.A.Br., and descriptions for the three long-established taxa, S. blepharolepis F.Muell., S. densifolia Hislop, Crayn & Puente-Lel. (until recently, Leucopogon flavescens var. brevifolius Benth.) and S. flavescens (Sond.) F.Muell. A new subspecies, subsp. stirlingensis Hislop, is recognised for S. flavescens. A morphological synopsis of the group is provided along with a key to species.

Nomination of a reference specimen for Amanita xanthocephala (Agaricales: Amanitaceae)

DAVISON, E.M., GIUSTINIANO, D., BOUGHER, N.L. AND BARRETT, M.D., Nuytsia 37: 17–32 (2026)

Details PDF
For Amanita xanthocephala (Berk.) D.A.Reid & R.N.Hilton we designate the specimen PERTH 08944555 from Kings Park as an informal reference specimen to complement the holotype K(M)236388, collected by Drummond from the Swan River Colony in 1843, and provide a description based on Western Australian collections. Sequences from the nuclear ribosomal transcribed spacer (ITS) region from the reference specimen and collections from Victoria and Western Australia cluster together in a well-supported clade. Amanita xanthocephala throughout southern Australia appears to be a single species. Amanita xanthocephala f. mcalpineana (Cleland & Cheel) D.A.Reid has a yellow pileus, however an ITS sequence published on the Atlas of Living Australia does not differ from those with an orange or reddish orange pileus, suggesting it is a common and variable species. Amanita xanthocephala f. mcalpineana is synonymised with A. xanthocephala.

Contributions to Orchidaceae in Western Australia: recognition of five new species

BROCKMAN, G. AND FRENCH, C.J., Nuytsia 37: 33–44 (2026)

Details PDF
Cyanicula micrantha G.Brockman & C.J.French, Paracaleana petraea G.Brockman, Paracaleana semota G.Brockman, Pterostylis inflata G.Brockman & C.J.French and Thelymitra congesta G.Brockman & C.J.French are formally named and described with photographs provided to aid identification. All have been assessed as warranting conservation-listing, with the exception of P. inflata.

A new desert mountain endemic from central Australia: Hysterobaeckea oreophila (Myrtaceae: Chamelaucieae)

ALBRECHT, D.E. AND RYE, B.L., Nuytsia 37: 45–50 (2026)

Taxonomic changes in six Western Australian genera of subtribe Hysterobaeckeinae (Myrtaceae: Chamelaucieae)

RYE, B.L., Nuytsia 37: 51–84 (2026)

Details PDF
Six genera belonging to the subtribe Hysterobaeckeinae Rye & Peter G.Wilson of Myrtaceae tribe Chamelaucieae DC. are updated to allow a more comprehensive coverage of them in the electronic Flora of Australia. The anther morphology of these genera is described, and the distinguishing characteristics of their diaspores are discussed and illustrated. Six poorly known, geographically restricted new species are described for the genera Anticoryne Turcz., Babingtonia Lindl., Scholtzia Schauer and Tetrapora Schauer as A. pallinup Rye, A. vallicola Rye, B. latifolia Rye, S. hortiorum Rye, S. nolba Rye and T. ostentata Rye, and one better known, but still geographically restricted, species is named S. viatica Rye. In Hysterobaeckea (Nied.) Rye, a species that had previously been included under Malleostemon J.W.Green with the phrase name M. sp. Officer Basin (D. Pearson 350) is described as H. uniloculata Rye, expanding the definition of Hysterobaeckea to include a 1-locular ovary, and a second new species is named H. lubrica Rye. One new species of Malleostemon is named as M. sparsus Rye now that additional material is available for it, although it may prove to be a hybrid. Scholtzia umbellifera F.Muell. and S. sp. Folly Hill (M.E. Trudgen 12097) are reduced to synonymy under S. obovata (DC.) Schauer, and the subspecies of S. brevistylis Rye are abandoned. Two phrase-named taxa under Baeckea L. are transferred to the appropriate genera to become Babingtonia sp. Dandaragan (G. Paczkowska s.n. PERTH 08245606) and Tetrapora sp. Youndegin Hill (A.S. George 15772). The new combination Tetrapora leptophylla (Turcz.) Rye is made based on Harmogia leptophylla Turcz., with lectotypifications for both this name and its synonym Baeckea floribunda Benth. Lectotypes are also nominated for Babingtonia camphorosmae (Endl.) Lindl., Scholtzia eatoniana (Ewart & Jean White) C.A.Gardner, S. involucrata (Endl.) Druce and S. laxiflora Benth. New or updated species keys and new descriptions of previously named species or genera are included where appropriate. The ten newly named species occur in the southern half of Western Australia and nine of them have conservation priority, including one that is presumed to be extinct.
