Description

Quassia indica is a shrub or tree that can reach up to 20 m tall.

The leaves are simple, elliptical-oblong to lance-shaped, measuring 12-30 cm x 4-12 cm, with prominent veins, and with pitted glands on both surfaces. The petiole is 1-2.5 cm long.

The inflorescence is a terminal or axillary pseudo-umbel. It is 1-30 cm long. The flowers are bisexual with 4-lobed sepal, free petals, accrescent, measuring up to 3 cm x 1 cm and creamy green to violet.

The fruit is an aggregate of the 4 carpels, laterally compressed, with a straight inner and semicircular outer margin and measures 4-9 cm x 2.5-5 cm. The seed is with thin testa, absent endosperm, plano-convex cotyledons and measuring up to 3.5 cm x 2.5 cm.
