野牡丹族数量分类的初步研究

用ＵＰＧＭＡ聚合法对野牡丹族的４２个性状进行Ｒ分析和对该族华南及台湾地区１５个分类群进行Ｑ分析．Ｒ分析的结果反映了性状之间相关进化及性状与分类群之间相关进化的规律性．Ｑ分析对这些分类群的分类系统做了初步的定量研究．其结论与经典分类基本吻合．Ｑ分析的结果还支持将台湾产的耳药花并入野牡丹属。

A PRELIMINARY RESEARCH ON THE NUMERICAL CLASSIFICATION OF THE TRIBE MELASTOMATEAE

R analysis of 42 characters of the tribe Melastomateae and Q analysis of 15 taxa in South China and Taiwan are studied with, UPGMA method. The results of R analysis show the regularities of mutual evolution of characters with characters and characters with taxa. The smaller the distance coefficient is, the stronger the level of mutual evolution of those. Two-stste characters are good ones in the classification of genera and the quantitative multistate characters vary even in one species.A preliminary quantitative study of systematics of these taxa is finished with Q analysis. The results are proximally identical with the classical taxonomy but it is suggested that Otanthera scaberrima is combined to the genus of Melastoma.
