Historical botanical records from Southeast Asia document the taxon Hyperanthera cochinchinensis as a synonym of the widely cultivated drumstick tree. Originally described from the Indochina region, this name represents a fast-growing deciduous tree adapted to tropical climates.
Although the name is no longer in active use by modern taxonomists, it remains an important reference in historical literature. It highlights the early documentation of tropical flora in Asia.
This species displays a corky bark and soft wood, often growing rapidly into a small or medium-sized tree. The leaves are tripinnate and feature numerous small, rounded leaflets arranged along a slender rachis.
Its white or cream-colored flowers are fragrant and grow in drooping clusters. The resulting seedpods are long, deeply ribbed, and contain three-angled seeds with thin wings.
The plant represented by this name is famous for its multipurpose utility, including edible leaves, pods, and roots. Additionally, the seeds are used for oil extraction and as a natural coagulant for water clarification.
Portuguese missionary and botanist João de Loureiro first described this species in his 1790 work Flora Cochinchinensis. The specific epithet refers to Cochinchina, a historical region in southern Vietnam where the plant was observed.
