摘要
通过对产自新疆的薄罗藓科5属8种的分类学研究,包括多毛藓属Lescuraea Bruch&Schimp.in B.S.G.的弯叶多毛藓L.incurvata(Hedw.)Lawton,密根多毛藓L.radicosa(Mitt.)Moeck.,石生多毛藓L.saxicola(Schimp.in B.S.G.)Mol.in Lor.;薄罗藓属Leskea Hedw.的薄罗藓L.polycarpa Hedw.;细罗藓属Leskeella(Brid.)Loeske的细罗藓L.nervosa(Brid.)Loeske;细枝藓属Lindbergia(C.Müll)Broth.的中华细枝藓L.sinensis(C.Müll)Broth.,以及假细罗藓属Pseudoleskeella Kindb.的假细罗藓P.catenulata(Brid.ex Schrad.)Kindb.和瓦叶假细罗藓P.tectorum(Brid.)Kindb.。其中,薄罗藓属Leskea Hedw.为新疆新记录属;薄罗藓Leskea polycarpaHedw.和密根多毛藓Lescuraea radicosa(Mitt.)Moeck.是新疆新记录种。根据标本形态特征,编制了新疆薄罗藓科植物分属、分种检索表,简要讨论了其生境和地理分布特点。
This paper is based on 105 specimens collected from Xinjiang Uygur Autonomous Region.The classification results show that there are 8 species of Leskeaceae in Xinjiang.They are Lescuraea Bruch Schimp.in B.S.G.[3 species: L.incurvata(Hedw.) Lawton,L.radicosa(Mitt.) Moeck.and L.saxicola(Schimp.in B.S.G.) Mol.in Lor.],Leskea Hedw.(1 species: L.polycarpa Hedw.),Leskeella(Brid.) Loeske(1 species: L.nervosa(Brid.) Loeske),Lindbergia(C.Müll) Broth.[1 species: L.sinensis(C.Müll) Broth.],Pseudoleskeella Kindb.[2 species: P.catenulata(Brid.ex Schrad.) Kindb.and P.tectorum(Brid.)Kindb.].Among them,the genus Leskea Hedw.,Leskea polycarpa Hedw.and L.radicosa(Mitt.) Moeck.are newly reported in this region.According to the studied specimens,the habitat and the geographic distribution of these species are discussed.The studied specimens are stored in the herbarium of College of Life Science,Xinjiang University.
