1. The present studies were undertaken primarily to describe and classify the Pinus pumila scrubs of Hokkaido in Japan on the basis of methodology of the Zurich-Montpellier school in phytosociology. 2. The investigations were carried out in the Daisetsu and the Hidaka ranges located in the central and southern parts of Hokkaido respectively. The homogenous parts of vegetation were analyzed by recording the dominance and sociability of all species including cryptogamic as well as vascular plants in the sample plot of 5×5m which well exceeds the minimal area needed. 3. The vegetations investigated were classified according to fidelity of species and species combination. The vegetation units employed in the studies are alliance, association, and subassociation. 4. The following three associations and seven subassociations were established in the studies, namely, Assoc. Sorbeto-Pinetum pumilae : Subassoc. spiraetosum aemilianae and leucothoetosum yezoensis ; Assoc. Rubeto-Pinetum pumilae : Subassoc. typicum, sorbetosum matsumuranae and ledetosum diversipilosi ; Assoc. Ledeto-Pinetum pumilae : Subassoc. typicum, and dicranetosum scoparii. Each of the associations classified was described in the table showing the floristic composition and the data of growing habitats. 5. The interrelations of the subassociations classified were examined on the basis of index of similarity.
