Two new species of Lepidosperma (Cyperaceae) occurring in the Perth area of Western Australia
BARRETT, R.L. AND WILSON, K.L., Nuytsia 23: 173–187 (2013)
Lepidosperma apricola R.L.Barrett is a new species from the Darling Range in Western Australia. An isolated population also occurs in Kings Park, in the heart of Perth. This species has been confused with L. leptostachyum Nees. in the past. Lepidosperma calcicola R.L.Barrett & K.L.Wilson is a new species from coastal dune systems on the west coast of Western Australia, which has been previously confused with a number of other taxa. It has been listed on FloraBase as Lepidosperma sp. Coastal Dunes (R.J. Cranfield 9963). Both are common species occurring in the Perth region of Western Australia (and more broadly in the South West Botanical Province) that have been unnamed up until now.
A revision of the south-western Australian genus Astartea (Myrtaceae: Chamelaucieae)
RYE, B.L., Nuytsia 23: 189–269 (2013)
Astartea DC. is a long-established, taxonomically difficult genus closely related to Cyathostemon Turcz. and Hypocalymma (Endl.) Endl. It is restricted to damp habitats of the South West Botanical Province of Western Australia. In this revision of the genus, 22 species are recognised, including 11 new species (A. cicatricosa Rye & Trudgen, A. decemcostata Rye, A. eobalta Rye, A. graniticola Rye & Trudgen, A. middletonii Rye, A. montana Rye, A. onycis Rye & Trudgen, A. schaueri Rye & Trudgen, A. reticulata Rye, A. transversa Rye and A. zephyra Rye & Trudgen) and one new subspecies (A. aspera Schauer subsp. riparia Rye). A presumed hybrid between A. arbuscula (R.Br. ex Benth.) Rye and A. corniculata Schauer is also described. Distinguishing characteristics, insect associations and other aspects of the biology of Astartea are discussed and illustrated.
Two new species of Westringia sect. Cephalowestringia (Lamiaceae: Westringieae) from the south-west of Western Australia
DAVIS, R.W. AND JOBSON, P., Nuytsia 23: 271–276 (2013)
Westringia fitzgeraldensis R.W.Davis & P.Jobson and W. ophioglossa R.W.Davis & P.Jobson are described here as new. A modification to the existing key for Westringia Sm. sect. Cephalowestringia Kuntze is provided to account for W. fitzgeraldensis and W. ophioglossa. Westringia fitzgeraldensis occurs in open mallee in the Fitzgerald River National Park and W. ophioglossa in mallee woodlands in the northern wheatbelt. A distribution map is provided.
