A Taxonomic Study of the Genus Polygonum in Hebei Province

In the course of field investigations, 29 species and 2 varieties of Polygonum have been found in Hebei Province. By comparing the characters of different species of Polygonum in this area, the authors made a detailed analysis to the systematic importance of morphodifferentiations of Polygonum. In this study, 29 species of Polygonum in Hebei Province were also used in numerical taxonomic treatment. According to the principle of clustering line method, a few lines which divide sections were respectively decided. The results of numerical research distinctively disagree with the scheme of classical classifications. Some reasons led to these differences have been discussed in this paper.
