摘要
本文在综合分析慈姑属分类研究工作的基础上,运用电子计算机对世界慈姑属植物进行了数量分类学研究。以该属全部已知种和部分种下单位45个作为分类运算单位,选取了30个生态学和形态学的分类性状。聚类分析的结果初步揭示了各类群间的亲缘关系。
Having reviewed briefly the studies of Sagittaria in the world,we deal with the numerical classification of Sagittaria in the present paper.Forty- five taxa and thirty ecological and morphological characters are selected. The result obtained through cluster analysis is preliminary conductive to the relationships among the taxa.
