中華叉苔

本文對我國西南地區叉苔科(Metzgeriaceae)進行了訂正，共計2屬7種、1亞種、1變種。對西藏、橫斷山脈及鄰區標本作了研究，把喜馬拉雅叉苔Metzgeria himalayensis Kashyap並於平叉苔日本亞種M.conjugata subsp.japonica(Hatt.)Kuwah．；把中華叉苔M．sinensis Chen作為狹尖叉苔M．consanguinea Schiffn.的異名。我國東北記載的長梗毛叉苔Apometzgeria longifrondis(Gao)Chang根據其特徵，應歸於毛叉苔細肋變種A．pubescens(Schrank)Kuwah.var.kinabaluensis Kuwah.本文還報道2箇中國新分佈種：藍叉苔M.darjeelingensis Kuwah.背胞叉苔M. novicrassipilis Kuwah ^[2] 

The genus Metzgeria Raddi in China was originally treated as a single genus in the family Metzgeriaceae until 1984. In some early years before 1984, Y. Kuwahara (1966,1968), a Japanese bryologist, recognized this group to be distinct and treated it under four genera: Metzgeria Raddi., Apometzgeria Kuwah., Austrometzgeria Kuwah., and Apertithallus Kuwah.The present study concerns the family Metzgeriaceae in China, especially in South west-ern China. 7 species, 1 subspecies and 1 variety belonging to two genera are discussed and illus-trated, among which, the M. darjeelingensis Kuwah. and M. novicrassipilis Kuwah. are new re-cords in China. Also the key to species is given.
