摘　　要：描述了采自中国浙江九龙山的苔类植物一新种——毛茎合叶苔Scapania paraphyllia T.Cao,C.Gao,J.Sun & B.R.Zuo。该新种与腋毛合叶苔S.bolanderi Aust.相近,两种皆具带齿叶片和假鳞毛,但新种具如下特征可与腋毛合叶苔区别:(1)植物体小,通常红色;(2)假鳞毛多数,不分枝,不仅生于叶腋,茎上也有着生;(3)背脊为腹瓣长的1/4–1/3,背瓣为腹瓣大小的1/2–1/3;(4)叶角质层表面粗糙,具粗瘤,直径达6–8μm。与另一个相似种S.ampliata Steph.相比,因新种具有粗糙的叶表面和假鳞毛等特征,也易于区别。A new liverwort species, Scapania paraphyllia T. Cao, C. Gao, J. Sun ＆ B. R. Zuo, is described and illustrated from Zhejiang, China. The new species is closely related to S. bolanderi Aust. in having similar toothed leaves and pseudoparaphyllia. The former, however, differs from the later by having： （1） smaller plants; （2） pseudoparaphyllia numerous, not only growing on leaf axils but also on stems; （3） leaves divided into 1/4-1/3 of length and dorsal lobes as 1/3-1/2 size of ventral lobes; （4） cuticle of leaves rough, with large papillae up to 6-8 μm in diameter. The new species is also similar to S. ampliata Steph. with similar leaf shape and mouth of perianth. But it can be easily distinguished from the latter by having rough leaf cuticle and pseudoparaphyllia.
