Our analysis indicates that apocarpy is polyphyletic within the subclass Alismatidae. Two independent origins of apocarpy in Alismatidae are explored in this study.

研究结果表明离生心皮在泽泻亚纲中是多次独立起源的，据初步估计在泽泻亚纲中离生心皮可能有2次独立的起源。

The molecular phylogeny of Alismatidae based on analysis of chloroplast rbcL gene sequence data serves as a framework with which to evaluate character evolution with respect to the derivation of apocarpy in the group.

本文基於rbcL基因序列资料构建了泽泻亚纲的系统发育关系，依据此系统发育关系为框架，讨论了泽泻亚纲不同心皮的起源与演化，尤其是离生心皮的起源与演化。
