Grevillea zygoloba is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub with divided leaves, the lobes linear and more or less parallel, and clusters of creamy-white flowers.
Description
[edit]Grevillea zygoloba is an erect shrub that typically grows to a height of up to 2 m (6 ft 7 in) and has erect, glaucous branchlets. Its leaves are 50–80 mm (2.0–3.1 in) long and divided with usually 3 to 7, more or less parallel lobes sometimes divided again, the end lobes linear, 30–50 mm (1.2–2.0 in) long and 0.7–1.0 mm (0.028–0.039 in) wide. The edges of the leaves are rolled under, usually concealing the lower surface apart from the mid-vein. The flowers are arranged in leaf axils and on the ends of branches in sometimes branched clusters, the end clusters cylindrical to conical on a rachis 20–40 mm (0.79–1.57 in) long, the flowers nearer the base of the rachis opening first. The flowers are creamy-white, the pistil 6.5–7.5 mm (0.26–0.30 in) long. Flowering occurs from September to November and the fruit is a sticky, pimply, elliptic follicle 5–7 mm (0.20–0.28 in) long.[2][3]
