Triphyophyllum /ˌtrɪfi.ɵˈfɪləm/ is a monotypic plant genus, containing the single species Triphyophyllum peltatum. It is native to tropical western Africa, in Sierra Leone and Liberia, growing in tropical rainforests.
It is a liana, with a three-stage lifecycle, each with a different shaped leaf, as indicated by its Greek name. In the first stage, T. peltatum has simple lanceolate leaves, and looks nondescript. However, it then additionally develops long, glandular leaves, resembling those of the related Drosophyllum, which capture insects. The plant then enters its adult liana form, with short non-carnivorous leaves on a long twining stem.
T. peltatum is currently cultivated in only three botanical gardens: Abidjan, Bonn, and Würzburg. It is exceedingly rare in private collections.
