Description
editGrevillea centristigma is a low, compact to erect, rounded or spreading shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in). Its leaves are narrowly elliptic to egg-shaped with the narrower end towards the base, 15–40 mm (0.59–1.57 in) long and 2–9 mm (0.079–0.354 in) wide, with the edges turned down and both surfaces sparsely covered with long soft hairs. The flowers are arranged in groups of five to eight on the ends of branchlets and are deep yellow to orange, the pistil 5–6 mm (0.20–0.24 in) long and covered with long, soft hairs, the style yellow, turning brick red as it ages. Flowering mostly occurs from June to November and the fruit is a hairy follicle 8–12 mm (0.31–0.47 in) long.[3][4][5]
Taxonomy
editThis grevillea was first formally described in 1986 by Donald McGillivray who gave it the name Grevillea drummondii subsp. centristigma in his book New Names in Grevillea (Proteaceae).[6] In 1992, Gregory John Keighery elevated the subspecies to species status as Grevillea centristigma.[5][7] The specific epithet (centristigma) means "centre stigma".[8]
Distribution and habitat
editGrevillea centristigma grows in moist forest and is widespread between the Whicher Range, Collie and Walpole in the Jarrah Forest and Warren biogeographic regions of south-western Western Australia.[3][4][5]
Conservation status
editThis species is listed by the Government of Western Australia Department of Biodiversity, Conservation and Attractions as "not threatened" and as Least Concern on the IUCN Red List of Threatened Species.[1][4]
