Description

Grevillea brachystachya is a bushy shrub that typically grows to a height of 0.6 to 2 metres (2 to 7 ft) and usually has silky-hairy branchlets. The leaves are linear, 20–150 mm (0.79–5.91 in) long and 1–2 mm (0.039–0.079 in) wide with two longitudinal grooves on the lower surface. The flowers are arranged in more or less spherical groups on a rachis 4–8 mm (0.16–0.31 in) long, and are cream-coloured to greenish-cream. The pistil is 12–17 mm (0.47–0.67 in) long and glabrous. Flowering occurs from June to November and the fruit is a glabrous, oval follicle 17–21 mm (0.67–0.83 in) long.[2][3]

Taxonomy

Grevillea brachystachya was first formally described in 1848 by Carl Meissner in Johann Georg Christian Lehmann's Plantae Preissianae from specimens collected by James Drummond in the Swan River Colony.[4][5] The specific epithet (brachystachya) means "short flower spike".[6]

Distribution and habitat

Short-spiked grevillea usually grows in woodland or shrubland and is found in scattered populations between Miling, Wongan Hills and the Murchison River in the Avon Wheatbelt, Geraldton Sandplains and Yalgoo biogeographic regions of south-western Western Australia.[2][3]

Conservation status

Grevillea brachystachya is listed as "not threatened" by the Department of Biodiversity, Conservation and Attractions.[2]
