Distribution and Ecology

Probably endemic to NEQ, restricted to the Atherton Tableland and its immediate vicinity. Altitudinal range from 600-800 m. Grows in well developed upland rain forest and is usually found on deep red soils derived from basalt.

Natural History & Notes

Produces a useful general purpose timber suitable for house construction where not exposed to the weather. Particularly well suited for polished floors.

Wood specific gravity 0.91 Cause et al. (1989).
