Grevillea plurijuga is a species of flowering plant in the family Proteaceae and is endemic to southern Western Australia. It is a prostrate to low-lying or dense mounded to erect shrub with divided leaves with linear lobes and loose clusters of hairy, red or pink flowers.
Grevillea plurijuga is a prostrate to low-lying or dense mounded to erect shrub that typically grows to a height of 0.6–3 m (2 ft 0 in – 9 ft 10 in) and up to 3.5 m (11 ft) wide. Its leaves are 20–130 mm (0.79–5.12 in) long and mostly divided with 8 to 24 linear lobes 20–100 mm (0.79–3.94 in) long and 0.7–1.5 mm (0.028–0.059 in) wide, the edges rolled under, enclosing the lower surface apart from the mid-vein. The flowers are arranged in loose, more or less cylindrical clusters of 8 to 40 on a hairy rachis 20–100 mm (0.79–3.94 in) long. Flowering time and colour varies with subspecies and the fruit is a glabrous, prominently ridged follicle 12–17 mm (0.47–0.67 in) long.[2][3]
Taxonomy
Grevillea plurijuga was first formally described in 1864 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by George Maxwell.[4][5] The specific epithet (plurijuga) means "more yokes", referring to the many leaf lobes.[6]
In 2000, Robert Owen Makinson described two subspecies of G. plurijuga in the Flora of Australia, and the names are accepted by the Australian Plant Census:
- Grevillea plurijuga F.Muell subsp. plurijuga[7] is a prostrate to low-lying, dense, mounded shrub 0.3–2 m (1 ft 0 in – 6 ft 7 in) high with pale grey to pinkish-red and cream-coloured flowers from September to January. The flowers are mostly borne on long, trailing peduncles below the base of the foliage.[8][9]
- Grevillea plurijuga subsp. superba (Olde & Marriott) Makinson[10] (originally described in 1993 by as Grevillea superba in the journal Nuytsia by Peter Olde and Neil Marriott)[11][12] is a dense, robust shrub 2–4 m (6 ft 7 in – 13 ft 1 in) high usually with pale grey and cream-coloured or pale yellow flowers from October to December. The flowers are mostly borne on erect peduncles held above the foliage.[13][14]
