Description

Grevillea inconspicua is an erect shrub that typically grows to a height of 0.3–2.3 m (1 ft 0 in – 7 ft 7 in) and has silky-hairy branchlets. The leaves are crowded and circular in cross-section or linear, 5–25 mm (0.20–0.98 in) long, 0.5–1.5 mm (0.020–0.059 in) wide and silky-hairy. The flowers are arranged in usually branched clusters 10–20 mm (0.39–0.79 in) long on the ends of branches and are bright yellow or golden yellow, the pistil about 7 mm (0.28 in) long. Flowering occurs from September to November and the fruit is a cylindrical to oval follicle 10–16 mm (0.39–0.63 in) long.[2][3]
