A Cytological Observation on Six Mosses of Northeast China


 In this paper the chromosome number of 6 mosses species are reported.
The materials used for investigation were taken from immature capsules. Meiosis
in spore mother cells were observed, and the results are as follows: Brachythecium
plumosum, n=15. Entodon  obtusatus, n = 11. E.okamurae, n = 11.
Anoectangium  aestivum,  n= 13. Bryum  argenteum, n= 10. Eurhynchium
eustegium, n = 20+ 2m. The chromosome number of the former three species are re-
ported for the first time.
