Description

Acacia acrionastes is a spindly, glabrous shrub or tree that typically grows to a height of 2–8 m (6 ft 7 in – 26 ft 3 in). It has linear phyllodes that are 60–190 mm (2.4–7.5 in) long and 2–5 mm (0.079–0.197 in) wide and often narrower towards the tip. The flowers are arranged in a raceme 20–45 mm (0.79–1.77 in) long with 10 to 16 heads on a peduncle 3–6 mm (0.12–0.24 in) long, each head with 12 to 16 creamy yellow flowers. Flowering mainly occurs between July and August and the fruit is a leathery pod up to 100 mm (3.9 in) long and 8–10 mm (0.31–0.39 in) wide, containing up to nine seeds with a shiny black, club-shaped aril.
