Distribution pattern of Carex kobomugi OHWI was investigated with reference to the distance from seashore line in three sandy beaches including five stands of Shimane Prefecture , San'in Region . Contagious distribution denoting the statistically significant departure from randomness was observed in all stands. A definite correlation could not be recognized between the degree of contagiousness of distribution and the distance from the seashore line. Twin type of clumps were detected in four-fifths of eighteen distance-classes established in five stands. The smaller scale of clump was estimated to be 0.32 m^2 , while that of the larger one was to be 1.28 m^2-5.12m^2 . The frequency distribution of the actual clump sizes followed the lognormal distribution. The smaller scale of clump corresponded withthe maximum total clump area as a whole.
