葛属（Pueraria DC．）的分支分析

A CLADISTIC ANALYSIS OF PUERARIA DC.(LEGUMINOSAE)

摘要:

本文采用２４个形态性状对葛属进行了分支分析，得到了１１个最简约分支图和一个严格一致化分支图，葛属的种间关系。根据分支分析结果对ｖａｎｄｅｒＭａｅｓｅｎ的葛属分类系统提出了修订意见。

Abstract:

Using Teyleria and Glycine as outgoups, 11 equally most parsimonious cladograms of Pueraria are yielded from cladistic analysis based on twenty-four morphological characters. The motley assemblage named by Lackey is a group of cladistically most primitive species. The authors indicate that the species in subsections Pulcherrima and Pueraria of section Pueraria discribed by van der Maesen form a monophyly, and subsedion Nonnundiflorae (Section Pueraria)excluding P. imbricata, P.bella and P. alopecuroides, is another monophyly. The sectional status of P.phaseoloides is not warranted. Revisions of the classification of the genus are suggested.
