Morphology
This species is characterized by its exceptionally slender and delicate foliage, which is reflected in its specific epithet. The leaves are pinnately compound, featuring thin, lanceolate leaflets with finely serrated margins. Small, inconspicuous flowers are borne on slender racemes.
Like other bitterwood species, its tissues contain quassinoid compounds that give the plant a characteristically bitter taste. The fruit consists of small, reddish-black drupes containing a single seed.
Interesting facts
The name tenuifolia means thin-leaved in Latin, which serves as a major identifier in separating it from broader-leaved relatives like Brucea antidysenterica. Although first classified over a century ago, its remote natural habitats mean it remains rarely observed by modern field botanists.
