(1) In the present paper, the writers studied on the distribution of the section Crassinodi and Eusasa, and morphological variations as well as ecological performance of Sasa plants related to the Sections mentioned in mainly E. Hokkaido. (2) Morphological characteristics were examined by constant or inconstant appearance of characteristics such as the relative height of the highest culm bud, the relative node diameter, and hairiness on internodes, culm-sheaths and leaf-sheaths. (3) Based on the morphological characteristics examined, three Sasa types were distinguished : i. Crassinodi type, ii. Eusasa type and iii. Composite type. Composite type was subdivided into more three types : a. Composite-Crassinodi (Cc) type, b. Composite-Eusasa (Ce) type, and c. Intermediate-Composite (Ci) type. Although Composite types were found all over Hokkaido, the Cc type was confined in the Crassinodi area, the Ce type was limited in the Eusasa area, and the Ci type was recognized in transitional areas from the Crassinodi area to the Eusasa area in Hokkaido. (4) Crassinodi type is corresponding to Sasa plants of the sect. Crassinodi and Eusasa type to those of the sect. Eusasa. (5) It can be distinguished the Macrochlamys and the Eusasa from the Crassinodi by the authors' numerical indexes. (6) In the distribution of the Crassinodi, the Crassinodi line proposed by S. Suzuki (1961) was not necessarily to be the demarcation line of the Crassinodi in Hokkaido, and especially in E. Hokkaido the Crassinodi-plants were found in habitats over 50 cm in max. snow depth.
