吕特拉科斯。l.包括31个分布在世界各地的主要高度独特的属。分支系统学分析的家庭进行了26个字符的解剖，花形态，花粉和种子形态。在四个外群假设中，柳叶菜科提供了最好的启发式评估，产生了3746棵树，树长为83，一致性指数和（C.I.）0.41的。一个严格的共识树从3746棵树产生了一个基础的单系群的五个属（海桑属，Duabanga，石榴，紫薇属，Lawsonia），其特征为花端（有限）花序和湿柱头，和第二支与blastotelic（无限）花序，干柱头，和减少心皮数。以柳叶菜科为外群的连续加权产生了5棵最简约的树，树长为164，C.I.的0.75。内部分支仅由7个非同质性性状弱支持。分析结果包括：（1）确定了千屈菜亚科的2个主要分支和7个单系群;（2）确定了千屈菜亚科（Lythraceae）的并系群。s.）;和（3）新大陆特有的属起源于一个以上古老的旧大陆进化系的迹象。该科目前的分类学分类与支序分析的结果并不密切相关。
The Lythraceaes. l.comprise 31 mostly highly distinctive genera distributed worldwide. Cladistic analyses of the family were undertaken using 26 characters from anatomy, floral morphology, pollen, and seed morphology. Of four outgroup hypotheses, the Onagraceae offered the best heuristic assessment, generating 3746 trees with a tree length of 83 and consistency index and (C.I.) of 0.41. A strict consensus tree from the 3746 trees produced a basal monophyletic group of five genera(Sonneratia, Duabanga, Punica, Lagerstroemia, Lawsonia)characterized by anthotelic (determinate) inflorescences and wet stigmas, and a second clade with blastotelic (indeterminate) inflorescences, dry stigmas, and reduced carpel number. Successive weighting with Onagraceae as outgroup generated five most parsimonious trees with a tree length of 164 and C.I. of 0.75. Internal branches are weakly supported by only seven non-homoplasious characters. Significant results of the analysis include: (1) recognition of the two major clades and a total of seven monophyletic groups within the family; (2) the paraphyly of subfamily Lythroideae (Lythraceaes. s.); and (3) indication that genera endemic to the New World have been derived from more than one ancient Old World evolutionary line. The current taxonomic classification of the family is not closely correlated with results of the cladistic analysis.
