山东省丛藓科苔藓植物研究

Pottiaceae in Shandong Province,China

通过对采自山东的5 500余号丛藓科苔藓植物标本进行整理、鉴定,得出山东省丛藓科苔藓植物24属79种3变种。其中中国新记录种一个,即木何兰小石藓Weissia muhlenbergiana(Sw artz)W.D.Reese&B.A.E.Lemmon;山东新记录属三个,即陈氏藓属Chenia R.H.Zander,疣壶藓属G ymnostomiella M.Fleisch.和托氏藓属Tuerckheimia Broth.;无齿红叶藓Bryoerythrophyllum gymnostomum(Broth.)P.C.Chen等28个山东新记录种。同时比较了2000年之前与之后采集标本的种类组成情况,发现差异明显,并对其原因进行了分析。本研究旨在明确山东丛藓科植物种类,同时为中国苔藓植物研究提供新的资料。

Based on the identification of about 5500 specimens collected from Shandong Province,79 species,3 varieties and 24 genera of Pottiaceae in Shandong Province are reported. Among them,Weissia muhlenbergiana( Swartz)W. D. Reese & B. A. E. Lemmon is found from China for the first time,while 3 genera,Chenia R. H. Zander,G ymnostomiella M. Fleisch. and Tuerckheimia Broth.,and 28 species are reported from Shandong Province for the first time. At the same time,the species composition based on the specimens collected before and after 2000 are compared,it is found that the difference is obvious,and the reasons are given. This study aims to clarify the species diversity of Pottiaceae in Shandong Province. At the same time,the study can provide newdata for the bryophyte researches of China.
