Grevillea evansiana

Grevillea evansiana is a low, dense, spreading shrub that typically grows to a height of up to 50 cm (20 in), rarely to 1.5 m (4 ft 11 in) and has branchlets covered with white, woolly hairs. Its leaves are usually elliptic, 25–60 mm (0.98–2.36 in) long and 3–10 mm (0.12–0.39 in) wide, the lower surface sillky-hairy. The flowers are arranged in more or less spherical clusters, usually on a peduncle 5–15 mm (0.20–0.59 in) long, on the ends of branchlets. The flowers are usually blackish-red with a burgundy style, rarely white with a greenish-cream style, the pistil 9–10 mm (0.35–0.39 in) long and the style strongly curved. Flowering occurs from August to December and the fruit is a glabrous, oblong follicle 10–12 mm (0.39–0.47 in) long.[2][3][4]

Grevillea evansiana was first formally described in 1953 by Hugh Shaw MacKee in Proceedings of the Linnean Society of New South Wales from specimens he collected near the Cudgegong River in the Rylstone area in 1951.[5][6] The specific epithet (evansiana) honours Obed David Evans.[6]

Evans grevillea usually grows in forest or woodland, sometimes in swampy heath and is only known from east of Rylstone in New South Wales.[2][3]

Grevillea evansiana is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the New South Wales Biodiversity Conservation Act 2016. The main threat to its survival is habitat disturbance and degradation due to recreational activities.[2][4][7]
