Description
editPlatysace cirrosa is a twining, tuberous, perennial herb or climber, that is usually leafless or with very small, tapering scale-like leaves. The flowers are arranged on the ends of branches in compound umbels with a few small, narrow involucral bracts and blunt, yellow, overlapping petals. Flowering occurs between January and March and the fruit is flatttened, about 6.5 mm (0.26 in) wide and 5.4 mm (0.21 in) long.[3][4]
Taxonomy
editPlatysace cirrosa was first formally described in 1845 by Alexander Andrejewitsch von Bunge in Lehmann's Plantae Preissianae.[5][6] The specific epithet (fruticulosa) means "bearing tendrils".[7]
Distribution and habitat
editThis platysace is found along slopes and drainage lines in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Yalgoo bioregions of south-western Western Australia where it grows in lateritic or loamy soils over granite.[3]
Conservation status
editPlatysace cirrosa is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[3]
