Description

Rhadinothamnus rudis is a shrub to 1.5 m (4 ft 11 in) high with terete, angular branchlets. The leaves are variable they may be wide or narrowly notched at the apex or almost circular, 7–35 mm (0.28–1.38 in) long, smooth edges, papery to leathery texture, smooth, on a short petiole. The white flowers are borne singly in leaf axils on an angular pedicel 3–10 mm (0.12–0.39 in) long, 2.5–3 mm (0.098–0.118 in) wide and the underside covered with small, silvery scales. The stamens marginally shorter than the petals. The fruit is a capsule about 5 mm (0.20 in) high, almost smooth, either with a short triangular point or with a blunt beak. Flowering occurs from January to December. [2] [3]

Taxonomy

This species was first formally described in 1845 by Friedrich Gottlieb Bartling and he gave it the name Phebalium rude, the description was published in Lehmann's Plantae Preissianae . [4] [5] In 1998 Paul G. Wilson changed the name to Rhadinothamnus rudis and published the name change in the journal Nuytsia. [6] [7]

There are three subspecies described by Paul Wilson and accepted by the Australian Plant Census:

Distribution and habitat

Rhadinothamnus rudis is found growing on hills and plains in clay, sand, rocky soils, limestone, laterite and quartzite from Albany to Esperance on the south coast of Western Australia. [2] [3]
