Quassia silvestris

Cheek & Jongkind

Simaroubaceae


There has been considerable confusion by botanists over this species, Quassia undulata and Quassia gabonensis, with all three at one time being treated as one species (as Quassia undulata). More recent research ('Two new names in West-Central African Quassia L. [Simaroubaceae]'; Martin Cheek & Carel C. H, Jongkind, Kew Bulletin Vol. 63 247-250 []) has concluded that these species are distinct, and this is the treatment that is followed here[

Other Uses

The heartwood is whitish to straw-coloured; it is not distinct from the sapwood. The texture is coarse; the grain irregular. The wood is not durable, being vulnerable to attack by decay fungi, stain, and termites; logs should be converted soon after felling or chemically treated to minimize degrade. It dries rapidly with little checking but warp is severe. It springs and splits severely during log conversion; dried stock saws, planes, and nails easily; it is easy to peel into veneers. The wood is usd for purposes such as boxes and crates, veneer, plywood, pulpwood and particleboard[
