Description

Grevillea granulosa is a compact to spreading shrub that typically grows to a height of 0.4–1.5 m (1 ft 4 in – 4 ft 11 in). Its leaves are linear, 35–160 mm (1.4–6.3 in) long, 1.2–2.5 mm (0.047–0.098 in) wide and silky-hairy, with the edges rolled under, enclosing most of the lower surface. The flowers are arranged in clusters of three to eight on a woolly-hairy rachis 0.5–6 mm (0.020–0.236 in) long. The flowers are red to orange, rarely yellow, the pistil 20–23 mm (0.79–0.91 in) long. Flowering occurs from July to October and the fruit is an oval or narrowly elliptic follicle 10–14 mm (0.39–0.55 in) long and ridged with a few shaggy hairs.[2][3]

Taxonomy

Grevillea granulosa was first formally described in 1986 by Donald McGillivray in his book New Names in Grevillea (Proteaceae), based on specimens collected by Alison Marjorie Ashby between Mullewa and Pindar in 1965.[4] The specific epithet (granulosa) means "abounding in small grains", referring to the leaf surface.[5]

Distribution and habitat

This grevillea grows in shrubland, mallee scrub, or woodland in the area between Wubin, Lake Moore and Yuna in the Avon Wheatbelt, Geraldton Sandplains and Yuna biogeographic regions of south-western Western Australia.[2][3]

Conservation status

Grevillea granulosa is classified 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.[6]
