Description

Asterolasia pallida is a woody, perennial herb that typically grows to a height of about Шаблон:Cvt and sometimes forms a rhizome. The leaves are elliptical, Шаблон:Cvt 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 Шаблон:Cvt long. The petals are white, elliptical, Шаблон:Cvt long, with rust-coloured and colourless, star-shaped hairs on the back, and there are fifteen to twenty-five stamens.[1][2]

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.[3][4]

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;[5]
  • Asterolasia pallida subsp. pallida has both colourless and reddish hairs on the back of the petals and has a widespread distribution on the Darling Range.[6][7]

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.[7][1]

Conservation status

Asterolasia pallida is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[2]
