Brachychiton rupestris, a member of the Sterculiaceae, is commonly referred to as the Queensland Bottle Tree, Queensland-Flaschenbaum, or the Narrowleaf Bottle Tree or Kurrajong. Sometimes referred to as boab or baobab, which in Australia normally refers to Adansonia gregorii. The common name refers to the characteristic trunk of the tree, which can reach a 2 m diameter. The height of the tree is less impressive, with a maximum height of 18-20 m, smaller in cultivation; the canopy spans 5-12 m in diameter. The characteristic bottle shape develops in approximately five to eight years. The species is endemic to Central Queensland to northern New South Wales and this individual imaged near Hughenden in December 2008.
