摘　　要：对山罗花和天柱山罗花的4个居群的15项形态特征进行了数值分析。结果表明:形态性状在4个居群间均存在一定程度的变异,居群间变异系数的平均值从小到大排列为:天柱山居群(天柱山罗花)、天柱山居群(山罗花)、黄山居群(山罗花)、鹞落坪居群(山罗花);天柱山罗花与山罗花种间的形态差异已达到极显著水平,山罗花的3个居群间部分性状也具有极显著的形态差异;以形态特征为基础的Q-聚类分析可以把天柱山罗花和山罗花聚为两类,但山罗花(天柱山居群)和其他2个居群在较远处聚在一起,R-聚类分析发现了强正相关关系、弱正相关关系、弱负相关关系的性状。Four populations of M. roseum and M. aphraditis and their 15 morphological characters were studied by numerical analysis. The results showed that ： （ 1 ） The morphological characters showed certain variation within 4 populations, the order of the variation level of them was in turn Tianzhushan （M. aphraditis） 〈 Tianzhushan （ M. roseum） 〈 Huangshan （ M. roseum） 〈 Yaoluoping （ M. roseum）. There existed remarkably significant morphological differentiations between M. aphraditis and M. roseum, some differentiations among the three populations of M. roseum also reached a remarkably significant level. In Q - analysis , M. aphraditis and M. roseum could be divided into two groups, but the population of Tianzhushan and the other two populations of M. roseum were clustered in far distance; In R - analysis, the characters of great positive correlation, infirm positive correlation and infirm negative correlation had been found.
