Abstract

Dockrillia striolata (Rchb.f.) Rauschert, known as the yellow rock-orchid, occurs in New South Wales, Victoria and along the east coast of Tasmania. Within Tasmania, populations occur on the islands of the Furneaux Group and on mainland Tasmania (Kelvedon Hills south of Swansea through to wukalina/Mount William in the northeast). The taxonomy of the species is revised, with subsp. chrysantha no longer recognised as distinct based on a morphological examination of flower size and other characters. The species is restricted to Devonian granite-type rocks and Jurassic dolerite, usually in near-coastal areas and in various vegetation types. A review of the conservation status indicates that the species does not qualify as threatened under the Tasmanian Threatened Species Protection Act 1995, with it being well reserved throughout its range, an extent of occurrence of ca. 7500 km2, represented by at least 30 well-defined subpopulations, no apparent historical or contemporary declines in any population parameters, nor any identifiable risks.
