Grevillea divaricata is a possibly extinct species of flowering plant in the family Proteaceae and is endemic to central New South Wales. It is a low shrub with linear leaves and small clusters of flowers on the ends of branchlets. It is only known from the type specimen, discovered in 1823. No live specimens have been found since then.
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.[3][4][5]
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).[4]
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.[6][7] The specific epithet (divaricata) means "widely spreading".[8]
