Description

Grevillea disjuncta is a low, mounded or spreading shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in). Its leaves are linear to more or less needle-shaped, 8–20 mm (0.31–0.79 in) long and 1–3 mm (0.039–0.118 in) wide, the upper surface ridged and the edges rolled under, obscuring the lower surface. The flowers are arranged in leaf axils and along the stems in spreading groups of usually up to four. The flowers are pale orange to bright red and green to yellow, the pistil 19.5–28 mm (0.77–1.10 in) long. Flowering occurs from April to September and the fruit is an oval follicle 9.5–14 mm (0.37–0.55 in) long with a few shaggy hairs.[2][3]

Taxonomy

Grevillea disjuncta was first formally described in 1868 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae.[4][5] The specific epithet (disjuncta) means "separated", referring to the small groups of flowers.[6]

Distribution and habitat

This grevillea grows in heath, shrubland and woodland mainly in the area between Dumbleyung, Nyabing and Pingrup in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions of south-western Western Australia.[2][3]

Grevillea disjuncta is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[3]
