Description

Grevillea muelleri is a shrub that typically grows to a height of 20–40 cm (7.9–15.7 in) and has silky-hairy branchlets. Its adult leaves are 25–100 mm (0.98–3.94 in) long, linear to narrowly oblong or narrowly lance-shaped, sometimes with a few irregular teeth and 2–5 mm (0.079–0.197 in) wide, sometimes divided and 3–17 mm (0.12–0.67 in) wide. Leaves on flowering stems are usually narrower and shorter with fewer lobes. The flowers are white to cream-coloured, usually near the ends of branches, sometimes branched, in more or less spherical clusters 10 mm (0.39 in) long on a rachis 0.2–0.5 mm (0.0079–0.0197 in), the pistil 5–6 mm (0.20–0.24 in) long. Flowering occurs from June to September and the fruit is an egg-shaped to elliptic follicle 7.5–9.5 mm (0.30–0.37 in) long.[2][3]

Taxonomy

Grevillea muelleri was first formally described in 1870 by George Bentham in Flora Australiensis from specimens collected by Ferdinand von Mueller at the summit of the Stirling Range.[4][5] The specific epithet (muelleri) honours the collector of the type specimens.[6]

Distribution and habitat

This grevillea grows in forest and tall shrubland and is mainly restricted to the Stirling Range National Park in the Esperance Plains, Jarrah Forest and Mallee bioregions of south-western Western Australia.[2][3]
