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]
It is found in the MacDonnell Ranges Bioregion of Central Australia. [1] The main population is on Undoolya station. [5]
It is generally found on steep south facing slopes on skeletal soils. [1] [5]
It is listed as "vulnerable" under both Commonwealth and Territory legislation. [1] [2] The major threat to its survival is frequent bushfires. [4]
