Abstract

The snake gourd genus, Trichosanthes, is the largest genus in the Cucurbitaceae family, with over 90 species. Recent molecular phylogenetic data have indicated that the genus Gymnopetalum is to be merged with Trichosanthes to maintain monophyly. A revised infrageneric classification of Trichosanthes including Gymnopetalum is proposed with two subgenera, (I) subg. Scotanthus comb. nov. and (II) subg. Trichosanthes, eleven sections, (i) sect. Asterospermae, (ii) sect. Cucumeroides, (iii) sect. Edulis, (iv) sect. Foliobracteola, (v) sect. Gymnopetalum, (vi) sect. Involucraria, (vii) sect. Pseudovariifera sect. nov., (viii) sect. Villosae stat. nov., (ix) sect. Trichosanthes, (x) sect. Tripodanthera, and (xi) sect. Truncata. A synopsis of Trichosanthes with the 91 species recognized here is presented, including four new combinations, Trichosanthes orientalis, Trichosanthes tubiflora, Trichosanthes scabra var. pectinata, Trichosanthes scabra var. penicaudii, and a clarified nomenclature of Trichosanthes costata and Trichosanthes scabra.
