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 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.

This paper advances knowledge of triggerplant diversity in monsoonal and arid Australia. The following 14 species are newly described: Stylidium aliforme Wege & Brennan (N.T.), S. anomalum Wege (W.A.), S. brachyotis Wege & Brennan (N.T.), S. brennanianum Wege, M.D.Barrett & A.R.Bean (W.A., N.T., Qld), S. contrarium Wege (N.T.), S. eludens Wege & A.R.Bean (Qld), S. incognitum Wege (W.A., N.T.), S. modicum M.D.Barrett, R.L.Barrett & Wege (W.A.), S. pezidium Wege, Brennan & S.J.Dillon (W.A., N.T., Qld), S. synaptum Wege, Brennan & A.R.Bean (W.A., N.T., Qld), S. tantillum Wege & Brennan (N.T.), S. torquatum Wege & Brennan (N.T.), S. tremendum Wege, M.D.Barrett & R.L.Barrett (W.A.) and S. youwanjela M.D.Barrett, R.L.Barrett & Wege (W.A.). Stylidium tenerrimum F.Muell. (W.A., N.T.) is recircumscribed and S. evolutum Carlquist (N.T.) reinstated to its original circumscription. Narrower circumscriptions of S. fissilobum F.Muell. (W.A., N.T.) and S. multiscapum O.Schwarz (W.A., N.T.) are presented and a lectotype designated for the latter. Stylidium tenerum Spreng. (N.T., Qld, P.N.G.) is placed into synonymy under S. uliginosum Sw. ex Willd. (south-east Asia), and S. symonii Carlquist (N.T.) synonymised under S. floodii F.Muell. (N.T., Qld). Stylidium elachophyllum A.R.Bean & M.T.Mathieson (Qld) and S. irriguum W.Fitzg. (W.A.) are recorded for the Northern Territory, while S. aquaticum A.R.Bean (N.T.) and S. capillare R.Br. (N.T., Qld) are recorded for Western Australia. A record of S. longibracteatum (W.A.) from Kata Tjuta in the Northern Territory is highlighted as having potentially unreliable locality information. Lectotypes are selected for S. claytonioides W.Fitzg., S. cordifolium W.Fitzg., S. irriguum W.Fitzg., S. rubriscapum W.Fitzg. and S. trichopodum F.Muell. Both S. pseudotenellum O.Schwartz and S. mitrasacmoides F.Muell. are treated as names of uncertain application. The existence of appropriated type fragments in Herbarium Lowrieanum, recently bequeathed to the Western Australian Herbarium, is noted.

An annotated dichotomous key and photographic guide to Stylidium Sw. ex Willd. in the Northern Territory is provided. Stylidium gemmatum Wege & Brennan is formally described, and S. stenophyllum A.R.Bean placed into synonymy under a broadly circumscribed S. pachyrrhizum F.Muell.
