- Fruit: Produces drupaceous fruits containing seeds adapted to tropical dispersal mechanisms.
Interesting facts
The taxonomic history of this species involves multiple reclassifications, having been placed in the genera Quassia, Simarouba, and Aruba before settling in Simaba. Its species name, obovata, directly references the characteristic egg-shaped leaflets that are broader at the upper end. Like other members of its genus, it contains bitter quassinoids that deter herbivores.
