In considering phytogeography, the family or the genus in phanerogams in the modern sense could be treated as nearly equivalent to the genus or the species in Musci (Anderson 1963, Ochi 1982). The six phytogeographical kingdoms, Holarctic, Paleotropical, Neotropical, Cape, Australian and Holantarctic, have recently been adopted, with respect to phanerogams, mainly on the basis of the existence in these areas of many endemic and richly represented families, positively accepting the Theory of Continental Drift, by which such plants had been strongly affected in differentiation or distribution (Mattick 1964, Takhtajan 1986). Endemic and richly represented genera of Musci are far fewer or even absent in such kingdoms and there exist many far more widely distributed genera such as cosmopolitan, widespread, amphitropical temperate, Afro-American, Australia-Holantarctic ones, etc. These peculiar distributional patterns of mosses may not only be due to much smaller disseminules which could be dispersed long distances quickly, especially from west to east, but also to other particular characters of gametophytic disseminules, such as deficiency of photoperiodism. It may be difficult or even impossible, however, to either accept or deny the existence of such phytogeographical kingdoms throughout the above discussions on the distribution of mosses.
