Description

Grevillea calcicola is a much-branched shrub that typically grows to a height of 2 to 4 metres (7 to 13 ft). Its leaves are pinnatisect, 70–200 mm (2.8–7.9 in) long with two to seven linear lobes 1.3–2.5 mm (0.051–0.098 in) wide with the edges rolled under. The flowers are arranged in groups 60–70 mm (2.4–2.8 in) long on the ends of branchlets, and are off-white to creamy-white, the pistil 11.5–12.0 mm (0.45–0.47 in) long. Flowering occurs from May to August and the fruit is a glabrous follicle 21–27 mm (0.83–1.06 in) long.[2][3][4]

Taxonomy

Grevillea calcicola was first formally described in 1968 by Alex George in the Journal of the Royal Society of Western Australia from specimens he collected in the Cape Range National Park in 1961.[4][5] The specific epithet (calcicola) means "limestone-dweller".[6]

Distribution and habitat

This grevillea grows in low mallee shrubland in rocky or stony limestone soils and is restricted to the Cape Range west of Exmouth in north-western Western Australia.[2][3]

Conservation status

Grevillea calcicola is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]
