Conospermum stoechadis subsp. sclerophyllum is a shrub endemic to Western Australia.

Description

As with other forms of C. stoechadis, it grows as an erect, multi-stemmed shrub, with a lignotuber. It has slender needle-like leaves from two to 17 centimetres long and 0.6 to 2.25 millimetres wide, and panicles of white flowers.^[1][2] This subspecies grows to a height of from 0.3 to 1.5 metres, rarely to 2.5 metres, and has tomentose, grey leaves.^[3][4]

Taxonomy

It was first published at species rank as Conospermum sclerophyllum, in John Lindley's 1839 A Sketch of the Vegetation of the Swan River Colony, based on unspecified material.^[5] In 1995, Eleanor Bennett demoted it to a subspecies of C. stoechadis in her treatment of Conospermum for the Flora of Australia series of monographs.^[6][7]

Distribution and habitat

It occurs on sandplains of white, grey or yellow sand, or amongst laterite. It extends from Jurien Bay, east to Kulin, and south as far as Wickepin.^[3][4]

Ecology

It is not considered threatened.^[4]
