Keywords:Malesian Fabaceae, Derris in Thailand and Malesia
The relationship between Derris Lour. and several re lated genera [Aganope Miq., Brachypterum (Wight & Arn .) Benth ., Ostryocarpus Hook.f., Paraderris (Miq.) R. Geesink, Xeroderris Roberty] was studied using ph ylogenetic analysis.· The cladistic analysis resulted in a fairly well supported majority rule concensus cladogram. which lead to the recognition of Aganope. Derris, Ost1yocarpus. and
Paraderris as independent genera: Brachypterwn is reunited with Derris, and Xeroderris is united with Aganope. The species of Agan.ope, Derris. and Paraderris occurring in Thailand and Malesia are enumerated.
