20.1 Since the checklist of mosses of China being prepared by Paul L. Redfearn, Jr., et al. (1994 & 1995 versions) is the most comprehensive account of the names of Chinese mosses, contributors should consult the names of all relevant species, subspecies and varieties listed in this checklist. This checklist regularly updates the nomenclature of previously published names. The revised version of the checklist will be in press in 1995. Those names that are not being accepted for the Moss Flora of China (English version) should appear in synonymy or in discussion.
20.2 Authors are expected to check the following major floristic works published in Chinese. Contributors are also responsible for the recent literature related to their groups.
