Leaves - are simple or divided, with one or more narrow leaf blades up to 11 cm long and 2 cm wide.

Pods - follows flowering with small woody boat-shaped follicles that ripen from November to May.

Flowering September to November.

Indigenous uses - roots of young plants were a food source and also tapped for water. Fibrous inner bark, seeds after roasting and secretions from the trunk that were induced by wounds were all consumed.


As a drought deciduous succulent tree, it adapts readily to cultivation and is tolerant of a range of soils and temperatures. It is a key component and emergent tree in the endangered central semi-evergreen vine thickets—also known as bottletree scrub—of the Queensland Brigalow Belt. Remnant trees are often left by farmers on cleared land for their value as shade and fodder trees.
