Grevillea acropogon Makinson

Grevillea acropogon is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of southwestern Western Australia. It is a prostrate to erect shrub with pinnatisect leaves with five to seven sharply-pointed lobes, and red flowers.


Grevillea acropogon is a prostrate to erect shrub that grows to a height of up to 1.8 m (5 ft 11 in) with softly-hairy young branchlets. The leaves are 15–25 mm (0.59–0.98 in) long and pinnatisect with five to seven lobes, sometimes the lobes further divided. The lobes are linear, sharply-pointed, 10–18 mm (0.39–0.71 in) long and 0.8–1.1 mm (0.031–0.043 in) wide. The flowers are red and arranged in groups of 18 to 24 on a flowering stem 12–17 mm (0.47–0.67 in) long, each flower on a pedicel 2.0–2.5 mm (0.079–0.098 in) long, the pistil 18–22 mm (0.71–0.87 in) long. Flowering occurs from June to September.[2][3]

Grevillea acropogon was first formally described in 2000 by Robert Owen Makinson in the Flora of Australia based on material collected near Lake Unicup, west of Frankland, in 1996.[2][4] The specific epithet (acrobotrya) means "bearded at the end".[5]
Distribution and habitat

This grevillea is only known from the type location, where it grows in heathland in winter-wet situations.[2]
Conservation status

Grevillea acropogon is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Biodiversity, Conservation and Attractions. Only five individuals were known in 2015 but after a fenced enclosure was constructed the population increased to 275 in 2014. In 2009, 150 seedlings were introduced to a new site. The main threats to the species include damage by vehicles, drought, trampling by kangaroos and changes in hydrology.[3][6][7][8]
