Grevillea coccinea

Grevillea coccinea is a low-lying or prostrate shrub that typically grows to a height of 0.7–3 m (2 ft 4 in – 9 ft 10 in). Its leaves are narrowly wedge-shaped to linear, 25–125 mm (0.98–4.92 in) long and 1.0–4.5 mm (0.039–0.177 in) wide. The edges of the leaves are rolled under, obscuring all but the lower mid-vein, and the tips are usually sharply-pointed. The flowers are arranged in groups in leaf axils on a rachis 25–65 mm (0.98–2.56 in) long and are white, cream-coloured, and red or yellow, the pistil 19–23.5 mm (0.75–0.93 in) long with a glabrous style. Flowering occurs from March to December and the fruit is a silky-hairy follicle 10.5–16 mm (0.41–0.63 in) long.[2][3]

Grevillea coccinea was first formally described in 1855 by Carl Meissner in Hooker's Journal of Botany and Kew Garden Miscellany.[4][5] The specific epithet (coccinea) means "scarlet".[6]

In 1993, Peter M. Olde and Neil R. Marriott described two subspecies in the journal Nuytsia and the names are accepted by the Australian Plant Census:

• Grevillea coccinea Meisn subsp. coccinea[7] has a perianth 2–3 mm (0.079–0.118 in) wide and covered with silky hairs;[8][9]
• Grevillea coccinea subsp. lanata Olde & Marriott[10] has a perianth 3.0–3.5 mm (0.12–0.14 in) wide and covered with woolly hairs.[11]

This grevillea grows in shrub or heath and is found in southern Western Australia from Mount Manypeaks to near Hopetoun in the Esperance Plains and Mallee biogeographic regions of Western Australia. Subspecies lanata is confined to the Fitzgerald River National Park.[2][3][8][11]

This grevillea is listed as "not threatened" by the Department of Biodiversity, Conservation and Attractions,[2] but subspecies lanata is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[9] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[12]
