Recent research into plants formerly included in Bauhinia (see Wunderlin, R.P. 2010. Reorganization of the Cercideae (Fabaceae: Caesalpinioideae). Phytoneuron 2010-48: 1-5.) has reorganized the species of Bauhinia into 9 genera. Although not universally accepted as yet (2011), we are following this new treatment because it has been taken up by several authorities including GRIN, Flora of North America[
] and African Flowering Plants[
Bauhinia carronii F.Muell.
Common Name: Queensland Ebony
Queensland ebony is an evergreen or briefly deciduous tree, though often multi-stemmed, growing about 10 metres tall[
]. The tree usually retains its leaves, but in very dry conditions will shed most or even all of them[
The native Aborigines used to harvest the nectar from the flowers as a sweet food, though it is unclear if this practice is still carried out today.

A tree of the subtropical to tropical areas of Queensland.
Grows best in a sunny position[
]. Prefers a fertile, well-drained but moisture-retentive soil[
Nectar - raw[
]. The flowers secrete a considerable quantity of nectar that can either be sucked out or washed out with water[
The wood is light-brown, but becoming much darker towards the centre. It is hard, heavy, close-grained. It is considered to be suitable for cabinet-work[
Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.
