Morphology

This woody plant grows as a slender shrub or small tree under forest canopies. It displays pinnate leaves with multiple leaflets that feature a characteristic shape.

Distinct features of this species include:

  • Leaflet Tips: Strongly acuminate or tapering to a sharp point, which gives the species its botanical name.
  • Flowers: Small, unisexual flowers clustered in narrow, elongated panicles.
  • Fruit Structure: Oval drupes with a thin pericarp and a hard endocarp enclosing the seed.

Applications

Biologists study the chemical profile of this species due to the presence of bitter quassinoids. These compounds serve as defense mechanisms against herbivores and attract pharmaceutical interest.

Interesting facts

The name acuminata describes the sharp, tapering tips of the leaflets, a key diagnostic feature for field identification. Its bitter leaves are rarely consumed by local herbivores due to protective secondary metabolites.
