Derris trifoliata is a common woody climber found usually at the landward side of mangroves. It has imparipinnate compound leaves, with 3 to 7 leaflets, each being elliptic or ovate. The twining stems are often covered with lenticels.


Interesting Facts:

Derris species are well-documented for their fish stupefying and poisoning properties (Giesen et al., 2006). In Eastern Indonesia, local communities even grow their own varieties of Common Derris with stronger chemical properties to catch fish. The stem is also said to be very durable and used as ropes.
