| 摘 要： | 采用数值分类学方法,初步研究了我国5属19种木通科植物和大血藤科植物的系统分类.木通科与大血藤科二者具有不同质的规定性,从表型上看,分类关系并不密切;猫儿屎属和串果藤属在木通科的分类地位十分孤立;野木瓜属、牛姆瓜属、木通属可能隶属同一枝系,共同构成了木通科系统分类的主干或核心.

| Abstract: | Using the method of numerical taxonomy,we study the 5 genra,19 species of Lardizabalaceae and Sargentodoxaceae.Easedon the result of calcuation,we discuss the relationship and the systematic position between the two families. In the paper,we point out the different nature and heridity background of Lardizabalaceae and Sargentodoxaceae,the isolated taxonomic placement of Decai- snea and Sinofranchetia.We also point out that Akebia,Stauntonia,and Hol- boellia have closer relationship.Perhaps they belong to one group and form a main part or centre of systematic evolution of Lardizabalaceae. |
