摘　　要：选取 2 6个性状 ,应用不加权算术平均配对法对来自云南各地的 2 0份紫苏试材进行了数值分类学研究。结果表明 :这 2 0份紫苏试材可分成紫苏、回回苏、耳齿紫苏、野生紫苏和白苏 5个变种 ;并对白苏变种的设立和耳齿紫苏变种的分布进行了探讨。A numerical taxonomy of 20 samples of Perilla frutescens (L.) Britt. in Yunnan was studied by choosing 26 characters and using the UPGMA. The result of Cluster Analysis showed that 20 samples of Perilla frutescens (L.) Britt. in Yunnan could be divided into 5 varieties: var. crispa Deane ex Bailey, var. arguta (Benth.)Hand.-Mazz., var. auriculato-dentata C.Y. Wu et Hsuan , var. purpurascens (Hayata) H.W. Li and var. frutescens L.. The establishment of var. frutescens L. and distribution of var. auriculato-dentata were discussed.
