【摘要】 通过对十字花科独行菜族１５属３６种植物叶片脉序的观察，发现它们的脉序可分为５种类型，即：拟环结曲行羽状脉、环结曲行羽状脉、基出完全掌状脉、拟直行羽状脉、直行羽状脉，这些类型可做为区别属间的较好性状。在网眼大小、形状、发育状况，叶缘末级脉上又存在着共性，说明它们的亲缘关系较为密切，最后在系统演化上作了一些探讨。更多还原

【Abstract】 This paper had provided the fundamental information about the venation of 15 genera 36 species in Lepidieae (Crucifeae) and found it’s venationwas divided into 5 types: Brochidodromoides Brochiodromous Basal perfect Actinodromous, Craspedo dromoides, Craspedodromous. It was found that it is quite different in leaf venation among 15 genera, so it is a good taxonomic featurefor them. But its have common character in size shape and development situation of areole, marginal ultimate venation. So it has close relation. This paper made discussition in system evolution.更多还原
