对华东地区半夏属内５个种７个群体进行营养器官的比较解剖，结果发现：（１）半夏属有３种类型的气孔器；有晶簇和针晶两种类型的晶体，晶簇为原始性状；导管直径的进化趋势由小到大。这３种性状十分稳定，可用来判断类群的进化程度并作为半夏属药材组织鉴定的依据。（２）半夏是具有明显多态现象的复合种，性状的变异幅度很大，但很容易通过无融合生殖将基因型保存下来。（３）盾叶半夏、鹞落坪半夏较为原始，虎掌、半夏较为进化。（４）半夏可能由鹞落坪半夏进化而来。
The results showed that: (1) There are three types of stomatal apparatus in Pinellia ternata; two types of crystals, crystal cluster and needle crystal Clusters for the original character; catheter evolution trend from small to large. These three traits are very stable, can be used to determine the evolution of taxa and as a basis for identification of Pinellia is a tissue identification. (2) Pinellia ternata is a complex species with obvious polymorphism. The variation of traits is very large, but it is easy to save the genotype through apomixis. (3) Pinellia ternata, 鹞 off Ping Pinellia is more primitive, tiger’s palm, Pinellia more evolution. (4) Pinellia may have evolved from Pineapple Pinellia.
