Species
Nesogordonia papaverifera (A. Chev.) Capuron ex N. Hallé

Description
The sapwood is pink or brownish, clearly differentiated from the pinkish-brown heartwood, which turns purplish-red when exposed to air. The density varies from 0.65 to 0.85. Water pockets are common in the trunks, causing internal stress during drying, with the risk of cracking. Mechanical strength and durability are excellent.
Plant morphology

It is a medium-sized tree, up to 30 m tall, with a columnar and cylindrical trunk, sometimes ribbed at the base. The leaves are alternate, simple, with needle-like stipules, a pointed tip and a rounded base, covered with sparse stellate hairs. The flowers are pentamerous, borne in inflorescences at the leaf axils, and are creamy white in color. The fruit is an obconical capsule.
