5. Arrangement of taxa

5.1 The sequence of familial arrangements in the eight-volume printed Flora is more or less phylogenetic and roughly follows the Brotherus system (1924-1925). The basic arrangements of major families will be similar to that of P.-C. Chen as outlined in his books entitled Genera Muscorum Sinicorum, part I & II, Science Press, Beijing (1963, 1978). However, the circumscription of some families will reflect the present understanding of the groups or with modifications to be suggested by the editorial committee, if necessary. The sequence of genera and species within a family will be arranged alphabetically for ease of use.
