Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Native to the dense tropical forests of West and Central Africa, Nothospondias talbotii grows as a rare dioecious tree species. It is taxonomically recognized as a synonym of Nothospondias staudtii, the sole member of its genus.
The species is primarily distributed across countries such as Nigeria, Cameroon, Gabon, Ghana, and Côte d'Ivoire. Due to its limited occurrence and the ongoing pressure on its forest habitats, this tree is of interest to conservationists and botanists studying regional flora.
The tree has a straight, slender trunk covered with characteristic grayish bark. The leaves are compound, odd-pinnate, and spirally arranged on the branches. The leaflets are glossy, dark green, with pronounced venation and entire margins, which gives the crown a dense and spreading appearance.
The small flowers are gathered in branched paniculate inflorescences. The fruits are fleshy drupes with a tough skin, which acquire a reddish-yellow hue when ripe. Inside each fruit, there is a hard stone containing a single seed.
The plant was first described under the name Nothospondias talbotii by British botanist Spencer Le Marchant Moore. Later taxonomic revisions determined that it is identical to Nothospondias staudtii, which was established earlier by German botanist Adolf Engler.
As a dioecious species, individual trees of this taxon are unisexual, bearing either exclusively male or female flowers. This reproductive strategy requires both male and female trees to grow in proximity for successful pollination and fruit production.
