Acacia estrophiolata F.Muell.

A small tree 5-20 m high which grows upright. It can be 3-10 m across. The bark is thick, dark and with furrows in it. The bark comes off in patches. The branches stick upwards. The trunk can be 25 to 35 cm across. The leaves (phyllodes) hang down. They are long and narrow. This gives the tree a willow like appearance. It is a graceful weeping tree and one of the larger ones of inland Australia. The leaves are 4-10 cm long by 0.3 cm across. They are smooth and flat with 3 veins. Leaves on young trees are wider, shorter and spiny. Adult leaves look quite different. The flower heads are round balls about 0.5 cm across. They are pale yellow. The flower stalks can be 1 cm long and 1-2 can occur in the angles of leaves. The pods are 3-10 cm long and 0.6 cm wide. They are flat and narrow. They are dark brown and constricted between the seeds. When the pods fall, instead of splitting open they often break between the seeds. The seed is rather hard.

It suits hot dry places. It does well in well drained light to medium soils. It prefers full sun. It occurs in central Australia. It is common near Alice Springs. It is very drought tolerant. It is easily killed by fire. It can grow in arid places. It suits hardiness zones 9-10.

Bark from branches, root bark and gum is used traditionally by Northern Territory Aboriginal people for various skin disorders, upper respiratory tract infections and gastro-intestinal discomfort, according to Aboriginal Communities of the Northern Territory (1993), Traditional Aboriginal Medicines in the Northern Territory of Australia 12–13 (Conservation Commission of the Northern Territory of Australia, Darwin).

It is grown from seed.
