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:
- Asterolasia pallida subsp. hyalina has petals with only colourless hairs on the back of the petals and only occurs in the Dryandra State Forest south-east of Perth;[6]
- Asterolasia pallida subsp. pallida has both colourless and reddish hairs on the back of the petals and has a widespread distribution on the
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]
