The forest communities of the warm temperate zone in Kiyosumi region of the Boso Peninsula, were classified by the numerical method. Similarity between the plots was calculated from the data of the cover percentage and floristic composition of trees and climbers of the high tree layer. Three measurements of similarity, the angular coefficient, the standardized Euclidian distance and the coefficient of Jaccard, and one clustering technique (WPGMA) were practiced. Then three different dendrograms were obtained. As the different measurements of similarity produce different systems of classification, the synthesized technique treating these results was sought and practiced. The groups of plots which always belong to the same clusters in the three different dendrograms were designated as the vegetational "core". Each core was regarded as the unit of vegetation. Four forest types were found by considering the size and floristic composition of the cores, and finally 89 plots were classified into 14 forest units.
