Grevillea muelleri is a species of flowering plant in the family Proteaceae and is endemic to the a relatively small area of south-western Western Australia. It is a shrub with linear to narrowly oblong, or divided leaves with linear or narrowly egg-shaped lobes, more or less spherical clusters of white to cream-coloured flowers.
Grevillea muelleri is a shrub that typically grows to a height of and has silky-hairy branchlets. Its adult leaves are long, linear to narrowly oblong or narrowly lance-shaped, sometimes with a few irregular teeth and wide, sometimes divided and 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 long on a rachis, the pistil long. Flowering occurs from June to September and the fruit is an egg-shaped to elliptic follicle long.[1]
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.[2] [3] The specific epithet (muelleri) honours the collector of the type specimens.[4]
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.
