Description and Ethnobotany
| Growth Form | It is a shrub or tree that grows up to 10 m tall. Its young twigs are densely covered with brown hairs. |
|---|---|
| Foliage | Its spirally arranged, stalked leaves have thinly leathery leaf blades that are drop-shaped, and 7–37 by 2.7–11 cm. The leaf blades have toothed margins that vary in size. |
| Flowers | Up to 20 flowers are found in dense, almost stalkless clusters arising from the leaf axils of side branches. These flowers are mostly white to sometimes yellow, and facing upwards from the lateral branches. |
| Fruit | Its fruit is round, up to 3.5 cm wide, and covered in a dense mass of branched hairs before splitting open. Each fruit contains up to 6 seeds that are egg-shaped, glossy, straw-coloured, and 4–7 mm long. |
| Habitat | It grows in primary or secondary forests, in humid places, in the lowlands up to 600 m altitude. It occurs locally in the vicinity of the Upper Peirce Reservoir and MacRitchie Reservoir. |
| Associated Fauna | Its flowers are insect-pollinated. It is also the preferred local food plant for caterpillars of the butterfly, the royal Assyrian (Terinos terpander robertsia), the adult of which lays its eggs singly on the undersides of the leaf blades. |
| Cultivation | It can be propagated by seed. |
| Etymology | Latin Rinorea, from a Guyanese vernacular name; Latin anguis, snake; Latin ferre, to bear, referring to the twisted hairs on the fruits |
