The population structures, spatial and temporal distributions of individual plants, and survivorship were investigated in four Japanese Trillium species (Liliaceae), T. kamtschaticum, T. tschonoskii, T. apetalon and T. smallii. The stage class structures of these four species based on leaf area categories all showed similar depletion curves associated with an increase in stage class. That is, there occurs a conspicuous decrease in early juvenile stages, subsequent leveling-off in the intermediate stages and a slight decrease again in the larger stages. The high mortality in juvenile stages was also confirmed by continuous observations in the permanent plots established on the forest floor for T. kamtschaticum and T. apetalon. Furthermore, the analysis of spatial distribution patterns for T. kamtschaticum and T. apetalon revealed successive distributional changes from underdispersed (aggregated) to random or overdispersed with the progress of the growth stage.
