摘 要 ：本文是应用群分析研究薯蓣属根状茎组中国分类群分类的一次尝试。分类特征取用了形态学、细胞学、花粉形态和生物化学等多方面的性状进行综合分析；方法和手段上使用了距离系数、相关系数等各种群分析运算方法，并且以综合系数进行评价。不仅取得了与传统分类基本一致的分类结果，为该组植物的系统分类提供富有启发性的参考，同时也为高等植物数量分类研究找到一种最优分类方法一相关系数UPGMA法。

Abstract:This paper deals with the application of the numerical method in plant taxonomical rescarch. Using Sect. Stenophora Uline as an example, interspecific variability was measured by using methods of cluster analysis. Analysis with 36 phenetic char- acters (23 external morphological, 2 cytological, 3 palynological, 5 phytoche- mistrical, 3 geographical and distributional) supports the delimitation of the 18 species as distinct taxa on the hasis of correlation coefficient and distance coeff- icient. Comparing with Pei et Tings (1979) systematic studies, similar results were found with correlation UPGMA method for cluster analysis.
