Acacia brachyclada is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia.

Description

Acacia brachyclada is a dense, rounded to spreading or low-domed, sticky shrub that typically grows to a height of 20–50 cm (7.9–19.7 in), and sometimes has arching branches. The phyllodes are egg-shaped to elliptic or oblong, 2–7 mm (0.079–0.276 in) long and 2–4 mm (0.079–0.157 in) wide with a point on the end. The flowers are borne in spherical heads in axils on a peduncle 3–6 mm (0.12–0.24 in) long, the heads with 12 to 16 golden-yellow flowers. Flowering occurs from August to February, and the pods are coiled, firmly papery, glabrous, somewhat like a string of beads, 2.5–4.5 mm (0.098–0.177 in) long with inflated oblong seeds 3–4 mm (0.12–0.16 in) long. [2] [3]

Taxonomy

Acacia brachyclada was first formally described in 1912 by the botanist William Vincent Fitzgerald in the Journal of Botany, British and Foreign from specimens collected near Kellerberrin. [4] [5] The specific epithet (brachyclada) means 'short shoot or branch'. [6]

Distribution and habitat

This species of wattle has a scattered distribution between Kununoppin, Ravenshorpe and Mount Ridley north of Esperance in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee bioregions of south-western Western Australia. It is mostly found on gentle undulating plains and low lying areas where grows in clay, loam, sandy or calcareous soils in mallee scrub or woodland. [2] [3] [7]

Conservation status

Acacia brachyclada is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions. [7]
