Two new species from the Leucopogon distans group (Ericaceae: Styphelioideae: Styphelieae) and the reinstatement of L. penicillatus
HISLOP, M., Nuytsia 22 (1) :
Two new species, Leucopogon microcarpus Hislop and L. newbeyi Hislop are described and another, L. penicillatus Stschegl., previously reduced by Bentham (1868) to a variety of L. distans R.Br., is reinstated. All three are illustrated and their distributions mapped. A key is provided for all Western Australian taxa currently referred to the L. distans group (sensu Hislop & Chapman 2007). Lectotypes are designated for L. distans and L. reflexus R.Br. Taxonomic and nomenclatural notes pertaining to L. atherolepis Stschegl.and L. reflexus are also included.
Two new mallee box species (Eucalyptus sect. Adnataria ser. Lucasianae; Myrtaceae) from the Pilbara region of Western Australia
NICOLLE, D. AND FRENCH, M.E., Nuytsia 22 (1) :
Two new species are described, both which have previously been included in E. lucasii Blakely, viz: E. aridimontana D.Nicolle & M.E.French sp. nov., known from high mountain ridges of the Hamersley Range, and E. rowleyi D.Nicolle & M.E.French sp. nov., known from plains of the De Grey River catchment to the north-east of the Hamersley Range. Both species differ from E. lucasii in their adult leaves which age to green and/or glossy, and in their thickened pedicels and peduncles (among other characteristics). Eucalyptus lucasii, as now circumscribed, is a widespread species restricted to watercourses and flood-out plains south of the Pilbara region. A key to E. ser. Lucasianae Chippend. and distribution maps for E. lucasii, E. aridimontana and E. rowleyi are provided.
A new species of Gompholobium (Fabaceae: Mirbelieae) from the Pilbara bioregion of Western Australia
WILKINS, C.F. AND TRUDGEN, M.E., Nuytsia 22 (1) :
Gompholobium oreophilum C.F.Wilkins & Trudgen, a new species from the Pilbara bioregion of Western Australia, is described and compared to its close relatives G. karijini Chappill and G. polyzygum F.Muell. The different habitat preferences and the possible hybridisation between G. oreophilum and G. karijini, which is also endemic to the Pilbara, are discussed. A key and distribution maps are provided.
