Description

Asterolasia pallida is a woody, perennial herb that typically grows to a height of about 1 m (3 ft 3 in) and sometimes forms a rhizome. The leaves are elliptical, 10–25 mm (0.39–0.98 in) long and covered with star-shaped hairs on the lower side. The flowers are arranged in umbels of three to six in leaf axils and on the ends of branchlets, each flower on a thin pedicel 3–10 mm (0.12–0.39 in) long. The petals are white, elliptical, 4–8 mm (0.16–0.31 in) long, with rust-coloured and colourless, star-shaped hairs on the back, and there are fifteen to twenty-five stamens. [2] [3]

Taxonomy

Asterolasia pallida was first formally described in 1863 by George Bentham and the description was published in Flora Australiensis from specimens collected by James Drummond. [4] [5]

In 1998, Paul Wilson described two subspecies and the names are accepted by the Australian Plant Census:

Distribution and habitat

This species grows on laterite in jarrah - marri woodland on the Darling Range from near Perth to Manjimup. Subspecies hyalina is restricted to the Dryandra State Forest. [8] [2]

Conservation status

Asterolasia pallida is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [3]
