Acacia undoolyana (common names Sickle-leaf wattle, Undoolya wattle)[1] is a species of wattle native to central Australia.[3]
Acacia undoolyana is a shrub or small tree growing up to 15 m high and has persistent fissured bark. Both stems and phyllodes have a covering of minute flattened hairs, when young. The phyllodes are flat, linear to narrowly elliptic, and silvery when young but later a grey-green. They are sickle-shaped, are 120–220 mm long by 5–15 mm wide, and have a marginal basal gland and a prominent apical gland. They have multiple parallel nerves of which up to three are more prominent. The inflorescence is a yellow cylindrical spike on a hairy peduncle 3–6 mm long. The pods are linear and 50–110 mm long by 2–3 mm wide, and the seeds have a white aril.[1]
It flowers from June to September and fruits from August to December.[1]
