Grevillea rogersoniana

Grevillea rogersoniana is an erect shrub that typically grows to a height of 1–4 m (3 ft 3 in – 13 ft 1 in), but sometimes to as much as 8 m (26 ft). Its leaves are spatula-shaped to wedge-shaped, 40–100 mm (1.6–3.9 in) long and 4–35 mm (0.16–1.38 in) wide with 3 to 5 rounded teeth or shallow lobes on the end. Both sides of the leaves are silky-hairy at first, but soon glabrous. The flowers are arranged on the ends of branches in cylindrical clusters on a rachis 40–60 mm (1.6–2.4 in) long. The flowers are bronze-coloured in the bud stage, later reddish pink, the style pink with a cream-coloured tip, the pistil 14–18 mm (0.55–0.71 in) long. Flowering occurs from August to October, and the fruit is a glabrous, elliptic to more or less spherical follicle 13.5–20 mm (0.53–0.79 in) long.^[3][4][2]

Grevillea rogersoniana was first formally described in 1964 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens he collected near Shark Bay.^[5][6] The specific epithet (rogersoniana) honours "Mrs. W. Rogerson", who directed Gardner to this species in 1961.^[4][6]

Rogerson's grevillea grows in tall woodland or Banksia scrub on sand dunes in an area south of Shark Bay, in the Carnarvon, Geraldton Sandplains and Yalgoo bioregions of Western Australia.^[2][3]

Grevillea rogersoniana is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,^[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.^[7]
