Acacia asepala is a species of flowering plant in the family Fabaceae and is endemic to Western Australia. It is a diffuse, multi-branched shrub with reddish-brown branchlets, sharply-pointed, glabrous, needle-shaped phyllodes on short projections of the stems, spherical heads of bright, mid-golden yellow flowers, and narrowly oblong pods up to 40 mm (1.6 in) long.
Acacia asepala is diffuse and multi-branched shrub with reddish-brown branchlets and typically grows to a 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) tall and 1.0–1.7 m (3 ft 3 in – 5 ft 7 in) wide. The phyllodes are wikt:glabrous, thickly needle-shaped, 10–25 mm (0.39–0.98 in) long and mostly 1 mm (0.039 in) wide with stipules about 0.2 mm (0.0079 in) long at the base. The flowers are arranged in two spherical heads in axils on a peduncles 2 mm (0.079 in) long, each head 4 mm (0.16 in) in diameter with about 10 mid-golden yellow flowers. Flowering has been observed beginning in August, and the pods are narrowly oblong to S-shaped or circular, 10–40 mm (0.39–1.57 in) long and 58 mm (2.3 in) wide.[2][3][4][5]
Taxonomy
Acacia asepala was first formally described in 1999 by the botanist Bruce Maslin in the journal Nuytsia from specimens he collected in Frank Hann National Park in 1985.[2][6] The specific epithet (asepala) means 'without sepals'.[2]
Distribution and habitat
This species of Acacia grows in low eucalypts woodland in loam or sandy loam in three disjunct populations, south-east of Marvel Loch, near Forrestania and in the Frank Hann National Park in the Avon Wheatbelt, Coolgardie and Mallee bioregions of Western Australia.[2][5][4]
