Qualea rosea is a tree growing up to 45 metres tall. The bole can be free of branches for up to 20 metres and around 60cm in diameter[
The tree is harvested from the wild for its timber, which is used locally and also traded as a source of 'mandioqueira' wood.
S. America - French Guiana, Surinam.
Primary rainforests, usually on higher, non-inundated sites[
], though in some areas it may grow on sandy or clayish soils[
]. Found especially on forested slopes[

A resin obtained from the tree is used as a purgative[
The freshly cut heartwood is a pinkish brown, becoming light reddish brown with a definite coppery or golden look upon drying; it is not clearly separated from the 3 - 6cm wide band of cream-coloured sapwood. The grain is straight to sometimes interlocked - when interlocked grain is present, a mild wavy figure is apparent on the tangential
surface; texture is medium to coarse; lustre is high, but without the characteristic sublustre so well developed in many high-grade cabinet woods; the unseasoned wood has an unpleasant odour, but no distinctive odour or taste is evident in seasoned wood. The wood is moderately heavy, moderately hard; somewhat variable in decay resistance but, in general, is moderately durable. It seasons at a normal rate, with a high risk of checking and distortion; once dry it is poorly stable in service. It has moderately good working properties; saws and planes well; takes nails and screws well; glues satisfactorily; but requires care in polishing. However, it dulls saws and cutting edges rather quickly because of the accumulation of silica in the parenchyma and ray cells - stellite-tipped and tungsten carbide tools are recommended. Chipped or torn grain is likely to occur when roey grain is present, and fuzzy surfaces and tearing are apt to occur in boring[
]. The wood is used locally for such purposes as canoes, joinery, flooring, interior trim, furniture, and millwork. It has been used in the superstructures of bridges and has also been found suitable for packing cases, outside and inside sheathing, rafters, and implements[
