Floristic and vegetational or between-habitat diversity of epilithic bryophytes were studied for 31 boulders that are scattered on a forest-floor in Unzen National Park, Japan. Surface area of boulders and environmental diversity represented as light-intensity variety (brightness-darkness index) and as a combined index of area and light-intensity variety are good predictors of the number of species and of life-forms of epilithic bryophytes. A new index of between-habitat diversity was proposed and named index of vegetational diversity (IVD). It can be applied to the regional vegetation that is classifiable into community-types, even in the case that the community interrelations are phytosociologically multi-dimensional and that some of the classified communities have few or no species in common with the others. The surface area and environmental diversity are also good predictors of the vegetational diversity of the epilithic bryophyte communities studied. Floristic and vegetational diversity are significantly mutually correlated.
