Botanical Description

Ochrosia oppositifolia is a member of the Apocynaceae family. It is a shrub or tree that can reach up to 45 m tall while its trunk is up to 50 cm in diametre. [2]

The leaves are arranged in whorls of 3-4(-5), usually obovate, rarely elliptical, and measure (4.5-) 8-36 cm x (1.5-)3-18 cm. The leaf base is decurrent onto the petiole, often rounded to obtuse at apex but sometimes apiculate, rarely truncate or shallowly retuse and with petiole 1-6.5 cm long. [2]

The inflorescence is an axillary and terminal cyme, in whorls of 2-4, with peduncle 0.5-13.5 cm long, congested and many-flowered. The flowers are fra­grant, pedicellate, with ovate sepals, measure 1-2.2 mm x 0.7­1.6 mm, obtuse, thick and green while the petal tube is (4-)5-10 (-12) mm long. The petal lobes are narrowly elliptical, measure (4-)5-9(12) mm x 2-3 mm while the stamens are included. [2]

The fruit consists of 2 separate mericarps which are el­lipsoid or ovoid, measuring 5-8 cm x 3-5.5 cm while the mesocarp is fi­brous, unites with the stone, green and turns yellow when ripens. [2]

The seed is suborbicular to elliptical, measures 25 mm x 20 mm, thin and winged. [2]
