Description

Grevillea stenostachya is a compact, densely-branched shrub that typically grows to a height of 0.6–1.5 m (2 ft 0 in – 4 ft 11 in). The leaves are pinnatipartite to almost pinnatisect, 15–50 mm (0.59–1.97 in) long, usually with 3 to 5 lobes, the end lobes cylindrical, 5–20 mm (0.20–0.79 in) long and 0.7–1.5 mm (0.028–0.059 in) wide and sharply pointed. The flowers are usually arranged in clusters with 2 to 5 branches, each branch cylindrical and 25–40 mm (0.98–1.57 in) long. The flowers are greenish-white to creamy yellow with a cream-coloured to yellow style, the pistil 3.8–5.2 mm (0.15–0.20 in) long. Flowering mainly occurs in August and September, and the fruit is a wrinkled, oval follicle 7–8 mm (0.28–0.31 in) long.[2][3][4]

Taxonomy

Grevillea stenostachya was first formally described in 1936 by Charles Gardner in the Journal of the Royal Society of Western Australia from specimens he collected with William Blackall east of Meeberrie homestead, near the Murchison River in 1931.[5][6] The specific epithet (stenostachya) means "narrow flower spike".[4][7]

Distribution and habitat

This grevillea grows in scub or mallee between Hamelin Pool, Meekatharra and the Murchison River in the Coolgardie, Geraldton Sandplains, Murchison and Yalgoo bioregions in the west of western Western Australia.[2][3]

Conservation status

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