Abstract Tetrastigma (Vitaceae) comprises about 95 species widely distributed throughout subtropical and tropical Asia, and extending to Australia. The genus is best known for being the host plants of Rafflesia , with the largest flower in the world, and other members of Rafflesiaceae. The phylogeny of Tetrastigma , however, remains poorly known. Four plastid markers ( atpB ‐ rbcL , psbA ‐ trnH , trnL ‐ trnF intergenic spacers, rps16 intron) were employed to infer the first phylogeny of Tetrastigma . Our sampling included eleven reported host species of Rafflesiaceae, being scattered in seven major clades throughout the Tetrastigma tree. A Templeton test rejected the hypothesis of a single origin of the parasite‐host relationship between Rafflesiaceae and Tetrastigma . Analysis of 114 accessions representing 53 species and four varieties throughout the distributional range of the genus provided robust support for the monophyly of Tetrastigma , yet Tetrastigma was found to be nested within Cayratia . Tetrastigma subg. Palmicirrata from the Sino‐Himalayan region was nested within the large and widely distributed T . subg. Tetrastigma . Two major clades (clades A and F) in our phylogeny correspond to T . sect. Tetrastigma and T . sect. Carinata of subgenus Tetrastigma , respectively.
