摘要
朱砂根复合群——朱砂根(Ardisia crenata Sims)、红凉伞(A.crenata var.bicolor(E.Walker)C.Y.Wu&C.Chen)和岭南紫金牛(A.linangensis C.M.Hu)之间存在一些过渡类型,很难依据少数几个关键性状对它们明确划分。运用Anderson的形象化散点图和柱状图的方法对全国14个省区135份标本的9个性状进行了分析,结果表明,岭南紫金牛应为独立的种,支持将红凉伞进行归并。
Ardisia crenata complex include A. crenata Sims, A. crenata var. bicolor （E. Walker） C. Y. Wu ＆ C. Chen, and A. linangensis C. M. Hu. They are taxonomically perplexing. By means of conventional taxonomic methods, it is difficult to discriminate them from one another. Nine characters are analysed for the 135 specimens of this complex from 14 provinces of China by means of pictorialized scatter diagram and histogram. The results support the idea of merging A. crenata var. bicolor （E. Walker） C. Y. Wu ＆ C. Chen into A. crenata Sims, but do not support treating A. linangensis C. M. Hu as the synonym ofA. crenata Sims.
