Description

Grevillea divaricata is a shrub that typically grows to a height of up to about 40 cm (16 in) and sometimes forms a lignotuber. It has spreading, linear leaves, 8–13 mm (0.31–0.51 in) long and 0.5–0.6 mm (0.020–0.024 in) wide with the edges rolled under, obscuring the lower surface. The upper surface of the leaves is rough to the touch. The flowers are arranged on the ends of branches in loose clusters of up to four on a glabrous rachis 2–6 mm (0.079–0.236 in) long, the pistil about 16 mm (0.63 in) long. The flowers are probably red or red and cream-coloured. Flowering was recorded in April.[2][3][4]

This grevillea is similar to G. rosmarinifolia but has spreading (rather than erect) leaves, rough (rather than mostly smooth) leaves, and sometimes forms a lignotuber (never present with G. rosmarinifolia).[3]

Taxonomy

Grevillea divaricata was first formally described in 1830 by Robert Brown in the Supplementum primum prodromi florae Novae Hollandiae from specimens collected by Allan Cunningham in mountains north of Bathurst in 1823.[5][6] The specific epithet (divaricata) means "widely spreading".[7]

Distribution and habitat

Grevillea divaricata is only known from the type location north of Bathurst where it grew in open forest.[2][4]

Conservation status

This grevillea is listed as "endangered" under the New South Wales Government Biodiversity Conservation Act 2016.[3][4]
