Grevillea bronweniae

Grevillea bronweniae is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect shrub usually with more or less linear leaves, and wheel-like clusters of crimson flowers.

Description

Grevillea bronweniae is an erect shrub that typically grows to a height of 1.0 to 1.8 metres (3.3 to 5.9 ft). The leaves are linear to narrowly elliptic with the narrower end towards the base, 10 to 160 millimetres (0.4 to 6.3 in) long and 2 to 14 millimetres (0.08 to 0.55 in) wide with the edges curved down or rolled under. The flowers are arranged in wheel-like clusters in leaf axils and at the ends of stems, on a rachis 0.5–2.0 mm (0.020–0.079 in) long, and are scarlet. The pistil is 8–12 mm (0.31–0.47 in) long and hairy. Flowering occurs from June to November and the fruit is a woolly-hairy, narrow oval follicle about 15 mm (0.59 in) long.[2][3][4]

Taxonomy

Grevillea bronweniae was first formally described by botanist Gregory John Keighery in Nuytsia in 1990.[4][5] The specific epithet (bronweniae) honours Keighery's wife and botanist, Bronwen Keighery.[5]

The FloraBase of the Western Australian Herbarium gives this taxon the name Grevillea bronwenae.[2]

Distribution and habitat

This grevillea grows in low woodland between Nannup and Busselton in the Jarrah Forest and Swan Coastal Plain biogeographic regions of south-western Western Australia.[2][4]

Conservation status

Grevillea bronweniae 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.[6]
