华北地区野豌豆属的系统研究

A STUDY OF GENUS VICIA FROM NORTH CHINA

着重应用聚类分析方法对华北地区野豌豆属进行研究，确定本属中亚属，组及种的分界限；并且把变型窄叶大龙骨野豌豆（Ｖｉｃｉａｍｅｇａｌｏｔｒｏｐｉｓｆ．ｓｔｅｎｏｐｈｙｌｌａ）提升为种：矮野豌豆（Ｖ．ｈｕｍｉｌｉｓＲ．Ｈｅｓｔａｔ．ｎｏｖ．ｅｔｎｏｍ．ｎｏｖ．）。

In this paper,22 OTU's including all the species of Vicia in North- China were use in numerical toxonomic treatement.According to the principle of clustering line method ,threelines which divided subgenera,sections,species were respectively decided, the 22 OTU’s weredivided into 2 subgenera:Subgen. Faba and Subgen. Vicia,the latter were divided into 5sections:Sect.Vicia、Sect.Cracca、Sect.Ervum、Sect.Cassubicae、Sect.Vicilla,Based onthe value of distance coefficient、morphological characters,Vicia megalotropis Ledeb.fstenophylla Franch.was elevated to specific rank:V. humilis R. He stat.nov. et nom. nov.
