Acacia anomala

Acacia anomala has a slender rush-like habit and typically grows to a height of 0.2 to 0.5 metres (0.7 to 1.6 ft). Its upper stems are glabrous and have narrow wings similar to those of Acacia applanata. Its few phyllodes are linear to narrowly elliptic, 40 to 100 millimetres (1.6 to 3.9 in) long and 2 to 6 millimetres (0.08 to 0.24 in) wide, or sometimes absent. Its flowers are borne in spikes, mostly 10–30 mm (0.39–1.18 in) long on a peduncle 1–4 mm (0.039–0.157 in) long and are golden-yellow. There are dark brown bracteoles prominent at the bud stage, but fall off as the flowers open. Flowering occurs in August and September and the pods are linear, crusty, glabrous, up to 50 mm (2.0 in) long and 3–4 mm (0.12–0.16 in) wide with oblong seeds about 2.5 mm (0.098 in) long.

Chittering grass wattle has a very small range, confined to an area between Chittering, Swan and Kalamunda where it grows on the slopes of the Darling Range in lateritic soils. It is mostly found as part of Eucalyptus woodland communities.
