Abstract: In this paper the chromosome countings of 4 moss species are reported for the first time in China. The materials used for investigation were taken from immature capsules. Meiosis in spore mother cells and also mitosis in the case of Plagiomnium cuspidatum were observed, with the result: Didymodon constrictus, n=14, Entodon schensianus, n=10+lm; Plagiomnium cuspidatum, n=6, Cratoncuron jilicinum, n=10. The chromosome numbers ofthe former two species are reported for the first time.

Key words: Moss, Chromosome number, Didymodon constrictus, Entodon schen-
