Brachychiton rupestris, commonly known as the narrow-leaved bottle tree or Queensland bottle tree, is a tree in the family Malvaceae native to Queensland, Australia. Discovered and described by Sir Thomas Mitchell and John Lindley in 1848, it gained its name from its bulbous trunk, which can be up to 3.5 metres (11 ft) diameter at breast height (DBH).
