对西番莲科25属42种的grbcl、atpB、matK和18S rDNA序列进行了系统发育分析。对组合数据集的简约分析产生了一个最简约树，这与贝叶斯分析中的50%多数共识树非常相似。除3个节点外，所有节点的bootstrap支持度均超过50%。西番莲科（Passifloraceae s.l.）及其前科、雄草科（Malesherbiaceae）、西番莲科（sensu stricto）和特纳科（Turneraceae）的单系性得到了强有力的支持。西番莲科（Passifloraceae）和特纳科（Turneraceae）是姐妹，形成了一个紧密相连的分支。在西番莲科中，西番莲科和西番莲科都是单系植物。西番莲科和车头草科的属间关系与以往的分类系统大致相关。雌雄同体的形态特征可以更好地用于西番莲科属群的划分。其他形态特征如花冠和假种皮也进行了讨论。
A phylogenetic analysis of Passifloraceae sensu lato was performed usingrbcL,atpB,matK,and 18S rDNA sequences from 25 genera and 42 species. Parsimony analyses of combined data sets resulted in a single most parsimonious tree, which was very similar to the 50% majority consensus tree from the Bayesian analysis. All nodes except three were supported by more than 50% bootstrap. The monophyly of Passifloraceae s.l. as well as the former families, Malesherbiaceae, Passifloraceae sensu stricto, and Turneraceae were strongly supported. Passifloraceae s.s. and the Turneraceae are sisters, and form a strongly supported clade. Within Passifloraceae s.s., the tribes Passifloreae and Paropsieae are both monophyletic. The intergeneric relationships within Passifloraceae s.s. and Turneraceae are roughly correlated with previous classification systems. The morphological character of an androgynophore/gynophore is better used for characterizing genera grouping within Passifloraceae s.s. Other morphological characters such as the corona and aril are discussed.
