Description
editGrevillea pilulifera is an erect or spreading shrub that typically grows to a height of 0.3 to 1 metre (1.0 to 3.3 ft) and has many branches. Its leaves are linear to narrowly oblong, 3–60 mm (0.12–2.36 in) long and 0.5–11 mm (0.020–0.433 in) wide, the edges turned down or rolled under, the upper surface grainy and the lower surface softly-hairy when exposed. The flowers are arranged in small groups and are covered with white to cream-coloured hairs, the pistil 6.5–8.5 mm (0.26–0.33 in) long. The end of the style is glabrous, bright yellow at first, turning orange, then red as the flower ages. Flowering occurs from April to December and the fruit is a softly-hairy, oblong follicle 8–13 mm (0.31–0.51 in) long.[2][3]
Taxonomy
editThis species was first formally described in 1840 by John Lindley, who gave it the name Hakea pilulifera in A Sketch of the Vegetation of the Swan River Colony.[4][5] In 1917, George Claridge Druce changed the name to Grevillea pilulifera in The Botanical Exchange Club and Society of the British Isles Report for 1916.[6] The specific epithet (pilulifera) means "bearing a little ball", referring to the tight clusters of buds.[7]
Distribution and habitat
editWoolly-flowered grevillea is found among medium to low sized trees in scrubland or heathland on gravelly soil. It is widespread between Badgingarra, Busselton and Albany and is commonly found on the Darling Range.[2][3]
