The morphologically diverse Commelinaceae consist of 41 genera with c. 650 species. Previous phylogenetic studies have revealed paraphyly of some taxa, but some of the infrafamilial taxa and most of the genera remain to be tested. To investigate phylogenetic relationships of the infrafamilial taxa and to test their monophyly, likelihood and Bayesian analyses with partial rbcL, matK and accD sequences were performed using 75 species from 33 genera of primarily eastern and south-eastern Asian Commelinaceae, with members of Haemodoraceae and Hanguanaceae as outgroups. The analyses resolved the early-diverging lineages of Commelineae and supported the monophyly of Dichorisandrinae and non-monophyly of Amischotolype, Belosynapsis, Murdannia, Pollia and Aneilema. Based on phylogenetics and morphology, we suggest that Palisotinae and Streptoliriinae should be raised to tribal rank, establishing subtribes Cochliostematinae, Commelininae and Murdanniinae, whereas Porandra, Belosynapsis, Anthericopsis are synonymized under Amischotolype, Cyanotis and Murdannia, respectively. Rhopalephora and two Australian Pollia spp. are moved to Aneilema. With all aforementioned taxonomic additions and changes, we propose a new classification for Commelinaceae, consisting of two subfamilies, six tribes, seven subtribes and 37 genera.

Commelinaceae (Commelinales) 的系统发育学和亚科分类

形态多样的 Commelinaceae 由 41 个属组成，其中 c. 650种。以前的系统发育研究已经揭示了一些类群的并系，但一些亚科类群和大多数属仍有待测试。为了研究家族下类群的系统发育关系并测试它们的单系性，使用部分 rbcL、matK 和 accD 序列进行可能性和贝叶斯分析，使用来自主要东亚和东南亚 Commelinaceae 的 33 个属的 75 个物种，以及 Haemoraceae 和 Hanguanaceae 的成员作为外群。分析解决了 Commelineae 的早期分歧谱系，并支持 Dichorisandrinae 的单一系和 Amischotolype、Belosynapsis、Murdannia、Pollia 和 Aneilema 的非单一系。基于系统发育学和形态学，我们建议将 Palisotinae 和 Streptoliriinae 提升到部落等级，建立亚群 Cochliostematinae、Commelininae 和 Murdanniinae，而 Porandra、Belosynapsis、Anthericopsis 分别是 Amischotolype、Cyanotis 和 Murdannia 的同义词。Rhopalephora 和两个澳大利亚 Pollia spp。被转移到Aneilema。通过上述所有分类学的增加和变化，我们提出了一个新的 Commelinaceae 分类，由两个亚科、六个部落、七个亚部落和 37 个属组成。
