Size distributions of Polygonum weyrichii var. alpinum, a dominant species in a volcanic gravel desert on Mt. Fuji, Japan, were compared be-tween two habitats with different soil particle sizes. The study sites were divided into two types, i.e., the large-scoria site（L-site）and the small-scoria site（S-site）based on the soil parti-cle size. 10 quadrats were set up at each of the two sites and number of individuals, diameter, and number of inflorescences of P . weyrichii var. alpinum within the quadrats were recorded. The number of small individuals（less than 10 cm in diameter）growing on the S-site was higher than that on the L-site. The total number of inflores-cences showed no significant difference between the two sites. At the L-site the large scoria layer with little water supply seems to limit the seed-ling establishment. At the S-site the surface movement of fine scoria might injure the plants. Thus, the soil structure appears to strongly in-fluence the size distribution of P . weyrichii var. alpinum.
