Two new triggerplants (Stylidium; Stylidiaceae) from the eastern margin of the Swan Coastal Plain, Western Australia
WEGE, J.A., KEIGHERY, G.J. AND KEIGHERY, B.J.
Stylidium ferricola Wege & Keighery and S. korijekup Wege, B.J.Keighery & Keighery are newly described. Stylidium ferricola is endemic to the southern ironstones near Busselton and is distinctive in the genus on account of its compact, rosetted habit, narrowly-oblanceolate leaves with entire margins and a hair-like mucro, paniculate inflorescences, oblong to cylindrical hypanthia bearing glandular trichomes, and vertically-paired corolla lobes. Stylidium korijekup is known from a single population occurring on laterite soils near Harvey and is characterised by a cormaceous habit, petiolate leaves, glabrous scapes bearing scattered sterile bracts, paniculate inflorescences, glabrous hypanthia and calyces, creamy-yellow and laterally-paired corolla lobes, and six, oblong, red-tipped throat appendages. Both species are flagged as being of conservation concern.
