A new phylogenetic tribal classification of the grape family (Vitaceae).

Vitaceae (the grape family) consists of about 16 genera and ca. 950 species primarily distributed in tropical regions. The family is most well-known for the economic importance of grapes and is also ecologically significant with many species as dominant climbers in tropical and temperate forests. Recent phylogenetic and phylogenomic analyses of sequence data from all three genomes have supported five major clades within Vitaceae: (1) the clade of Ampelopsis, Nekemias, the African Rhoicissus, and Clematicissus; (2) the Cissus clade; (3) the clade of Cayratia, Cyphostemma and Tetrastigma, with the latter two nested within Cayratia; (4) the clade of Parthenocissus and Yua; and (5) the grape genus Vitis and its close tropical relatives Ampelocissus, Pterisanthes and Nothocissus, with Nothocissus and Pterisanthes nested within Ampelocissus. Based on the phylogenetic and morphological (mostly inflorescence, floral and seed characters) evidence, the new classification places the 950 species and 16 genera into five tribes: (1) tribe Ampelopseae J.Wen et Z.L.Nie, trib. nov. (47 species in four genera; Ampelopsis, Nekemias, Rhoicissus and Clematicissus); (2) tribe Cisseae Rchb. (300 species in one genus; Cissus); (3) tribe Cayratieae J.Wen et L.M.Lu, trib. nov. (370 species in seven genera; Cayratia, Causonis, “Afrocayratia”, “Pseudocayratia”, Acareosperma, Cyphostemma and Tetrastigma); (4) tribe Parthenocisseae J.Wen et Z.D.Chen, trib. nov. (ca. 16 spp. in two genera; Parthenocissus and Yua); and (5) tribe Viteae Dumort. (ca. 190 species in two genera; Ampelocissus and Vitis).
