中国丛本藓属的订正

研究了我国南北各地的丛本藓属标本３２６号,借阅了美国纽约植物标本馆（ＮＹ）,芬兰赫尔辛基大学标本馆（Ｈ）及日本服部植物研究所标本馆（ＮＩＣＨ）的有关本属藓类各种的原模式标本（Ｈｏｌｏｔｙｐｅ）等模式标本（Ｓｙｎｔｙｐｅ）及后选模式（Ｌｅｃｔｏｔｙｐｅ）,据模式特征,重新订正了本属各种及中国各地标本,将原定名为绿丛本藓（Ａｎｏｅｃｔａｎｇｉｕｍｅｕｃｈｌｏｒｏｎ（Ｓｃｈｗａｅｇｒ．）Ｍｉｔｔ）改为丛     

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.
