It is a large climber found commonly in coastal swamps of tropical coastal areas in South-East Asia. It is 3–5 meters long. Its leaves are alternate, pinnate, 12–20cm; leaflets 5, ovate, 6-10 com, acuminate, rounded at base. Flowers are 1cm in size, in axillary racemes 8–15cm. Pods are 3–4cm, flat, pale yellow in color.
The rotenoid 6aα,12aα-12a-hydroxyelliptone can be found in the stems of D. trifoliata. [3] In 1902 Kazuo Nagai, Japanese chemical engineer of the Government-General of Taiwan, isolated a pure crystalline compound from a closely related plant possibly Derris elliptica which he called rotenone, after the Taiwanese name of the plant 蘆藤 (Min Nan Chinese: lôo-tîn) translated into Japanese rōten (ローテン).
Derris pod, root, stem all are rich in poisonous rotenoids and used commonly in insecticide, piscicide and pesticide activities and also have sometimes caused human morbidity or mortality due to suicide attempts or accidental ingestion.
The larvae of Hasora hurama feed on D. trifoliata.
