中文摘要：

基于燕尾藓属（Bryhnia Kaurin）被处理为狭义青藓属（Brachythecium Schimp.s.str.）的异名,燕尾藓属已不复存在。笔者对原分布于中国的5种燕尾藓属植物进行了相应的分类学修订,结果如下：短尖燕尾藓（B.hultenii E.B.Bartram）、燕尾藓[B.novae-angliae（Sull.＆Lesq.）Grout]和毛尖燕尾藓（B.trichomitria Dixon＆Thér.）被移入狭义青藓属并处理为短尖青藓[Brachythecium hultenii（E.B.Bartram）Min Li＆Y.F.Wang]、燕尾青藓[B.novae-angliae（Sull.＆Lesq.）A.Jaeger]和东亚青藓[B.trichomitrium（Dixon＆Thér.）Huttunen,Ignatov,Min Li＆Y.F.Wang];短枝燕尾藓（B.brachycladula Cardot）被移入鼠尾藓属（Myuroclada Besch.）,并处理为羽枝鼠尾藓[M.longiramea（Müll.Hal.）Min Li,Y.F.Wang,Ignatov＆Huttunen]的异名;密枝燕尾藓[B.serricuspis（Müll Hal.）Y.F.Wang＆R.L.Hu]移入拟异叶藓属（Pseudokindbergia Min Li,Y.F.Wang,Ignatov＆B.C.Tan）,并处理为拟异叶藓[P.dumosa（Mitt.）Min Li,Y.F.Wang,Ignatov＆B.C.Tan]的异名。

英文摘要：

Since Bryhnia Kaurin（Bryophyta：Brachytheciaceae）has been reduced to a synonym of Brachythecium Schimp.s.str.,the genus does not exist yet.In this paper,five species of Bryhnia distributed in China were revised.Results are as follows：B.hultenii E.B.Bartram,B.novae-angliae（Sull. Lesq.）Grout and B.trichomitria Dixon Thér.are transferred into Brachytheciums.str.as Brachythecium hultenii（E.B.Bartram）Min Li Y.F.Wang,B.novae-angliae（Sull. Lesq.）A.Jaeger and B.trichomitrium（Dixon Thér.）Huttunen,Ignatov,Min Li Y.F.Wang;Bryhnia brachycladula Cardot is transferred into Myuroclada Besch.and reduced to a synonym of M.longiramea（Müll.Hal.）Min Li,Y.F.Wang,Ignatov Huttunen;Bryhnia serricuspis（Müll Hal.）Y.F.Wang R.L.Hu is transferred into the genus Pseudokindbergia Min Li,Y.F.Wang,Ignatov B.C.Tan.and treated as a synonym of P.dumosa（Mitt.）Min Li,Y.F.Wang,Ignatov B.C.Tan.
