Abstract: Reported in this paper are chromosome numbers of six species of Mnium from Qinling Range. The chromosome number of M. pseudolycopodioides,n=6,is reported here for the first time. The counts for M.marginatum and M.lycopoidioides,n=12 and n=6 respectively,agree with the previous reports,and those for M.laevinerve,M.heterophyllum and M.thomsonii,here all found to be n=6,differs from some or all previously published chromosome numbers for these three species.

Key words: Mnium, Mitosis, Meiosis, Chromosome numbers
