摘要:

本文着重运用聚类分析的方法,对河北地区堇菜属植物进行研究,确定本属中组和亚
    组的划分界限,并通过对形态学特征和地理分布式样的分析,确认蒙古堇菜(V. mongolica
    Franch.)和北京堇菜(V.pekinensis(Regel) W.Beck.)实属同一个种,北京堇菜不应作为
    独立的种存在。通过将美丽堇菜组(Sect.Melanium Ging.)与其它类群进行比较,发现差异
    很大,超出了组和组间的相似性范围,因而支持Juzepczuk(1949)将它提升为亚属的分类处
    理。

Abstract:

In this study, 23 OTU’s including all the species of Viola in Hebei  Provin-
ce were used in numerical taxonomic  treatment.  According to the  principle of clustering line
method, a few lines which divide sections, subsections and  species were   respectively decided.
The result of numerical research roughly coincides with the scheme of 3 sections and 4 subsec-
tions proposed by Gingins et al.. Based on the value of distance coefficient, morphological
characters and geographical distribution, the species V. pekinensis is reduced as a synonym of
V. mongolica.  The writer compared section Melanium with other sections with characters of
morphology, palynology, cytology, phytogeography as well as pollination ecology and sugges-
 ted a revision of systematic position of section Melanium.
