Category:Brachychiton rupestris of Boulia Shire, Central Western Queensland

Several Brachychiton rupestris, commonly known as the Queensland bottle tree, have been planted in the centre of Burke St, Boulia and in the yard of the Boulia Wildlife Haven. Its common name derives from its bulbous trunk, which can be up to 3.5 metres (11 ft) diameter at breast height. Reaching 10–25 metres (33–82 ft) high, the Queensland bottle tree is deciduous, losing its leaves between September and December. The leaves are simple or divided, with one or more narrow leaf blades up to 11 centimetres (4 in) long and 2 centimetres (0.8 in) wide. Cream-coloured flowers appear from September to November, and are followed by woody boat-shaped follicles that ripen from November to May.

As a drought-deciduous succulent tree, B. rupestris 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.
