迄今为止，Clusiaceae的系统发育模型仅基于形态学数据。作为一个额外的系统发育信息来源，我们对26种Clusiaceae植物的叶绿体基因rbcL进行了测序。DNA数据与先前公布的序列一起进行了进化分析。结果表明：水螅科作为水螅亚科或水螅族的姐妹群嵌套在水螅科内。在最近的基于形态的分类中，Kielmeyeroideae和Clusioideae亚科在很大程度上被认为是单系的。唯一的例外是Clusiella，它与Kielmeyeroideae而不是Clusioideae有联系。我们得出结论，采树脂蜜蜂的传粉是独立出现在clusiae和Clusioideae中。
Phylogenetic models of the Clusiaceae have so far been based on morphological data only. As an additional source of phylogenetic information, the chloroplast gene rbcL was sequenced for 26 species, representing all available genera of Clusiaceae. The DNA data were analyzed cladistically together with previously published sequences. The results show that the aquatic family Podostemaceae is nested inside Clusiaceae as the sister group of subfamily Hypericoideae or tribe Hypericeae. The subfamilies Kielmeyeroideae and Clusioideae, as delimited in recent morphology-based classifications, are largely supported as monophyletic. The sole exception is Clusiella, which links with Kielmeyeroideae rather than with Clusioideae. We conclude that pollination by resin-collecting bees arose independently in Clusiella and the Clusioideae: Clusieae.
