Grevillea hockingsii is a species of flowering plant in the family Proteaceae and is endemic to south-eastern Queensland. It is an erect shrub with oblong to narrowly elliptic leaves and clusters of reddish-pink flowers.

Description

[edit]

Grevillea hockingsii is a dense, erect shrub that typically grows to a height of 1.5–2 m (4 ft 11 in – 6 ft 7 in) high and has ascending, silky-hairy branchlets. Its adult leaves are oblong to narrowly elliptic, 40–140 mm (1.6–5.5 in) long and 4–18 mm (0.16–0.71 in) wide. The lower surface of the leaves is silky-hairy. The flowers are arranged in leaf axils or on the stems in clusters of two to ten 15–22 mm (0.59–0.87 in) long on a rachis 2–5 mm (0.079–0.197 in) long, each flower on a pedicel about 4 mm (0.16 in) long. The flowers are reddish pink, hairy and slightly rust-coloured, the pistil 13–17.5 mm (0.51–0.69 in) long. Flowering mainly occurs from June to December and the fruit is an elliptic to narrowly oval follicle 20–36 mm (0.79–1.42 in) long.[2][3]

[edit]

Grevillea hockingsii was first formally described in 2008 by Bill Molyneux and Peter M. Olde in the journal Telopea from specimens collected in the Coominglah State Forest, Queensland in 1989.[2][4] The specific epithet (hockingsii) honours Francis David Hockings who discovered the species in 1983.[2][5]
