The heartwood is dark brown or dark red-brown; it is clearly demarcated from the light brown or greyish-white sapwood which often has a green tinge. The texture is coarse and uneven; the grain fairly straight but sometimes interlocked, maybe lustrous when first cut; there is no distinctive odour or taste when dry. The wood is strong, moderately hard, moderately heavy to heavy, moderately durable and very difficult to treat. It seasons fairly slowly, without any defects except for some staining; shrinkage is very high. It is easy to work, easy to split, moderately easy to resaw and easy to cross-cut; planning is easy and the planed surface is smooth, it takes a good finish. A light hardwood, it is suitable for medium to heavy construction under cover, furniture making, packing cases and pallets. Some species split well and are used for shingles[, , , ].
Although the tree is of poor shape, it produces one of the most durable timbers in its native range, where it is widely used for house posts[].
The wood is a good fuel and can be used to make charcoal[].

Propagation

Seed - easy to germinate if sown fresh. Self-sown seedlings can be transplanted[].
