Observing the mode of spatial distribution of the plants in the plant communities in the fallows of the Tokyo Agriculture Experiment Station and the dune of Chikura Machi, Chiba Prefecture by means of the quadrats which are placed in a row in the region S_j (j=1,2,......, m) in Fig. 1 and by splitting each quadrat into a number of smaller quadrats, the present author found that (1) the mode of spatial distribution of the plants is shown by the expressions : [numerical formula] and that (2) the frequency distribution of the number of the plants in a smaller quadrat in the jth quadrat is shown by the Poisson distribution : [numerical formula] derived theoretically from stochastic processes, where N is the number of plants in the jth quadrat, d is the distance between the first quadrat and the jth quadrat, P_j (γ) is the probability of the appearence of γ plants in a smaller quadrat in the jth quadrat, and N_0,A, α, and μ_j are constants.
