General Information

Quivisianthe papinae is a deciduous tree usually growing up to 20 metres tall, occasionally to 30 metres. The bole is up to 50cm in diameter[].
The tree is an important source of timber for local construction in western and southern Madagascar, where it is often harvested from the wild[].
The tree has been recorded to be locally common in Madagascar, especially in forests near Morondava. However, little natural vegetation is left in this region, and Quivisianthe papinae may already be subject to considerable genetic erosion[]. It has not as yet been treated in the IUCN List of Threatened Species(2013).

Medicinal

A coumarin derivative has been isolated from the wood[].
The bark contains several oxygen-heterocyclic compounds that have not yet been identified[].
The seeds are rich in mexicanolide type limonoids and contain 2 triterpenoids[].

Other Uses

The heartwood is pale brown, with a purplish tinge when fresh; it is distinctly demarcated from the around 5cm wide band of pinkish sapwood. The grain is straight or sometimes interlocked; texture coarse. The wood is heavy; very hard; durable, also withstanding fungal attacks and suitable for use in contact with the ground or water. Shrinkage during drying is high and, once dry, the wood is somewhat unstable in service. It is not particularly difficult to work with stellite-tipped sawteeth and tungsten-carbide-tipped cutting tools; splitting is common during nailing and screwing, and pre-boring is recommended. The wood is used for heavy construction, including poles of houses and bridges, and for heavy carpentry, flooring, cabinet work, and indoor and outdoor joinery[].

Propagation

Seed - best sown as soon as it is ripe[].
