Description

Grevillea epicroca is a shrub that typically grows up to 1–2.5 m (3 ft 3 in – 8 ft 2 in) high and has branchlets with a few silky hairs. Its leaves are elliptic to lance-shaped, mostly 40–70 mm (1.6–2.8 in) long and 8–12 mm (0.31–0.47 in) wide, the lower surface with a few silky hairs pressed against the surface. The flowers are arranged in small groups near the ends of branchets on a rachis 10–25 mm (0.39–0.98 in) long. The flowers are red and silky-hairy, the style red or pinkish and more or less glabrous, and the pistil 16–20 mm (0.63–0.79 in) long. Flowering mainly occurs from November to May and the fruit is a follicle 18–24 mm (0.71–0.94 in) long.[2][3][4]

Taxonomy

Grevillea epicroca was first formally described in 2000 by Val Stajsic and Bill Molyneux in the Flora of Australia from specimens collected by Michael Crisp near Braidwood in 1976.[2][5] The specific epithet (epicroca) means "a transparent woman's garment", referring to the thin layer of hairs on the lower surface of the leaves.[6]

Distribution and habitat

This grevillea grows in moist forest on steep rocky slopes on the escarpment west of Moruya at altitudes between 700 and 1,000 m (2,300 and 3,300 ft) in south-eastern New South Wales.[3][4]
