中国四齿藓科的订正

A REVISION OF THE FAMILY TETRAPHIDACEAE OF CHINA

对中国四齿藓科的分类及分布进行了全面研究。据陈邦杰等前人报道，本科在中国分布仅１属１种。现经作者们搜集到的２３６份中国四齿藓科标本（原均被鉴定为四齿藓ＴｅｔｒａｐｈｉｓｐｅｌｕｃｉｄａＨｅｄｗ．），重新解剖观察后鉴定，发现除原有之广布种四齿藓外，尚有此次新发现的中国新分布种：疣柄四齿藓ＴｅｔｒａｐｈｉｓｇｅｎｉｃｕｌａｔａＧｉｒｇ，另有傅星及高谦等在川西发现新分布原丝藓Ｔｅｔｒｏｄｏｎｔｉｕｍｂｒｏｗｎｉａｎｕｍ（Ｄｉｃｋｓ）Ｓｃｈｗａｅｇｒ．，以及Ｈ．Ｖｉｌ和曹同在吉林发现的无助原丝藓Ｔｅｔｒｏｄｏｎｔｉｕｍｒｅｐａｎｄｕｍ（ＦｕｎｃｋｅｘＳｔｕｒｍ）Ｓｃｈｗａｅｇｒ．，故本科在中国分布增至２属４种，本文对此４种在中国及世界分布均进行了讨论。

To fully understand the family Tetraphidaceae of China, based on an old collection, which only reported one genus and a single species, Tetraphis pellucida Hedw. The authors have examined 236 specimens, and have found and added some species of the family to the Bryoflora of China recently. An example is found in Tetraphis geniculata Girg. ex Mild., and Tetrodontium repandum (Funck ex Sturm) Schwaegr collected by Cao Tong, and H. Vitt from Prov. Jilin, Tetrodontium brownianum (Dicks.) Schwaegr collected by Fu Xing and Gao Qian from Sichuan. Therefore, there are about 2 genera and 4 species distributed in China. The distribution pattern of the above 4 species is discussed in this paper.
