New south-western Australian members of the genus Petrophile (Proteaceae: Petrophileae), including a hybrid

RYE, B.L., HISLOP, M., SHEPHERD, K.A. AND HOLLISTER, C., Nuytsia 21 (2): 35–67 (2011)

Four additional species are recognised in the genus Petrophile R.Br. ex J.Knight by the reinstatement of P. axillaris Meisn. and the description of three new species, P. globifera Hislop & K.A.Sheph., P. foremanii Hislop & Rye and P. septemfida Rye & K.A. Sheph. A hybrid between P. ericifolia R.Br. and P. seminuda Lindl. is documented, the new subspecies divaricata Hislop & K.A.Sheph. is named for P. conifera Meisn., and a lectotype is selected for P. seminuda var. indivisa Benth. There is also a key for members of the genus occurring in Western Australia, excluding those belonging to Petrophile sect. Arthrostigma (Endl.) Kuntze.

Stackhousia stratfordii (Celastraceae: Stackhousioideae), a remarkable new species from a remote location near Norseman, south-west Western Australia

BARKER, W.R. AND COCKERTON, G.T.B., Nuytsia 21 (2): 69–74 (2011)

Stackhousia stratfordii W.R.Barker & Cockerton sp. nov. possesses attributes unique to its genus and subfamily of opposite sub-radical leaves and flowers borne in scapes and containing three stamens. Morphological evidence is summarised arguing its placement within Stackhousia . The Stackhousioideae Burnett are a subfamily distinctive in Celastraceae R.Br. for their herbaceous life-form, mainly moth-pollinated, tubular flowers, and fruits that are single-seeded indehiscent mericarps (cocci) (Barker 1983, 1984, in press); in terms of diversity they are centred in Australia, occurring in much of the continent, in temperate arid, semi-arid and sub-tropical regions. Until recently a separate family (Stackhousiaceae R.Br.), the subfamily has morphological and geographic features unique in the family Celastraceae, in which they have been placed in the last decade (Kubitzki 2004a, b; Simmons 2004 a, b). It comprises three genera: Tripterococcus Endl. with three species , confined to south-west Western Australia, Macgregoria F.Muell., a single species spread across the southern half of arid Australia, and Stackhousia Sm. with over 30 species spread over the geographical and climatic range of the subfamily in Australia, with a single species in New Zealand and another spread into Malesia, the Philippines and Micronesia (Barker, in press).

New, locally endemic taxa in Leucopogon (Ericaceae: Styphelioideae: Styphelieae) from the Perth and midwest regions of Western Australia

HISLOP, M., Nuytsia 21 (2): 75–89 (2011)

Four new taxa, Leucopogon maritimus Hislop, L. nitidus Hislop, L. stokesii Hislop, and L. squarrosus Benth. subsp. trigynus Hislop are described and mapped; the first three are illustrated. All have very restricted distributions and are of high conservation priority. Lectotypes for L. squarrosus and L. brachycephalus DC. var. heterophyllus Sond. are designated.
