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.

Revision of the multi-ovulate species of Thysanotus (Asparagaceae), with three new species

MACFARLANE, T.D. AND FRENCH, C.J., Nuytsia 35: 55–76 (2024)

The group of Thysanotus species having more than two ovules per ovary locule (the multi-ovulate species) is taxonomically revised. The three previously described species, T. brachyantherus Brittan, T. lavanduliflorus Brittan and T. nudicaulis Brittan, are maintained and redescribed, with T. nudicaulis being redefined following removal of two new species previously included in its concept. Three new species are described: T. argillaceus T.Macfarlane & C.J.French, T. ellipsoideus T.Macfarlane & C.J.French and T. prospectus C.J.French & T.Macfarlane. The South Australian records of T. nudicaulis are recognised as belonging to T. ellipsoideus. A key to the group and illustrations of some characters are provided and all species are mapped and illustrated photographically.

Typifications in Malleostemon, Micromyrtus, Scholtzia and Thryptomene (Myrtaceae) and a nomenclatural update

WEGE, J.A. AND RYE, B.L., Nuytsia 35: 77–81 (2024)

As part of revisionary work in Myrtaceae tribe Chamelaucieae, lectotypes are selected for Malleostemon decipiens (W.Fitzg.) Trudgen, M. tuberculatus (E.Pritz.) J.W.Green, Micromyrtus imbricata Benth., M. sulphurea W.V.Fitzg., Scholtzia ciliata F.Muell., S. teretifolia Benth., S. uberiflora F.Muell. and Thryptomene kochii E.Pritz., and the type of Micromyrtus erichsenii Hemsl. is clarified. Micromyrtus chrysodema Rye is hypothesised to be a hybrid between M. flaviflora (F.Muell.) J.M.Black and a 2-ovulate, white-flowered species of Micromyrtus Benth.
