Grevillea rogersoniana | |
Grevillea rogersoniana, commonly known as Rogerson's grevillea, [2] is a species of flowering plant in the family Proteaceae and is endemic to a restricted area near Shark Bay in Western Australia. It is an erect shrub with spatula-shaped leaves with 3 to 5 teeth or shallow lobes on the end, and cylindrical clusters of reddish pink flowers, the style with a cream-coloured tip.
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]
