Phylogenetics and a revised classification of Vitaceae.

Vitaceae (the grape family) consists of about 15 genera and 900 species primarily distributed in tropical regions. The family is well-known for grapes (species of Vitis L.) and is ecologically important because many species are major climbers in tropical and temperate forests. Recent phylogenetic analyses have suggested five major clades within Vitaceae and the need to redefine several genera. These five major clades include: (1) the clade of Cayratia Juss., Cyphostemma (Planch.) Alston and Tetrastigma (Miq.) Planch., with the latter two nested within Cayratia; (2) the Cissus L. clade; (3) the clade of the grape genus Vitis and its close relatives Ampelocissus Planch., Pterisanthes Blume and Nothocissus (Miq.) Latiff from the tropics, with Nothocissus and Pterisanthes nested within Ampelocissus; (4) the clade of Parthenocissus Planch. and Yua C.L. Li; and (5) a clade of Ampelopsis Michx. and its close relatives (the African Rhoicissus Planch., the Australian Clematicissus Planch. and a small clade of about five species of Cissus from South America), as the first diverged lineage within Vitaceae. The genus Ampelopsis in the traditional sense is paraphyletic, and has been recently split into two genera: Ampelopsis and Nekemias Raf. The phylogenetic evidence supports the recognition of 15 genera in Vitaceae: Acareosperma Gagnep. (1 sp., poorly known from Laos), Afrocayratia gen. nov. (10 spp.), Ampelocissus (110 spp., including 20 species of Pterisanthes, and the type species of Nothocissus), Ampelopsis (15 spp.), Causonis Raf. (25 spp.), Cayratia (25 spp.), Cissus (350 spp.), Clematicissus (7 spp.), Cyphostemma (150 spp.), Nekemias (9 spp.), Parthenocissus (c. 15 spp.), Rhoicissus (12 spp.), Tetrastigma (80 spp.), Vitis (70 spp.), and Yua (2 spp.). Causonis and Afrocayratia are segregate genera from Cayratia. Nekemias is a segregate of Ampelopsis. Clematicissus is now expanded to include five Neotropical species in the Cissus striata Ruiz & Pavon complex, and represents a genus with an intercontinental disjunction between Australia and the Neotropics.
