Medicinal

The leaves are soaked in water overnight, or maybe hot water is poured over them, and the liquid allowed to become cold. It forms a somewhat mucilaginous liquid and is said to be very efficacious as a remedy for diarrhoea and dysentery. I understand that in some parts of the North it is quite an article of trade, not only in North Queensland but in the Northern Territory and right over to the North-West of Western Australia[

The heartwood is pale brown, becoming grey-brown upon exposure; it is not well defined from the paler coloured sapwood. The texture is fine and even; the grain is straight or interlocked. The wood is moderately hard to hard, heavy. It is suitable for light to medium purposes under cover; these uses include veneer and plywood, tool handles, general utility furniture, flooring, cladding, wooden pallets, mouldings and possibly sport equipments[

Propagation

Seed - we have no specific information for this species but seed of this genus is generally best sown as soon as it is ripe. Stored seed has a hard seedcoat and may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!), allowing the mix to cool somewhat and then leaving it in a warm place to soak for 12 - 24 hours. Sow the seeds in situ or in a nursery seedbed or trays - do not allow the compost to become dry. Germination and early growth are usually quite quick.
Cuttings - best taken with a heel.
