中文摘要：

根据历年采自新疆各地区的350号木灵藓属Orthotrichum植物标本,在查阅大量文献的基础上,通过经典分类学方法,对新疆木灵藓属植物进行了整理、鉴定和分类。结果表明：新疆有木灵藓属植物5亚属、17种,包括裸孔亚属subg.Gymnoporus（6种）、直叶亚属subg.Orthophyllum（1种）、疣叶亚属subg.Pulchella（5种）、圆孔亚属subg.Phaneroporum（1种）、木灵藓亚属subg.Orthotrichum（4种）,其中高山木灵藓Orthotrichum alpestre Hornsch.ex B.S.G.为中国新记录种;中国木灵藓O.hookeri Wils.ex Mitt.、东亚木灵藓O.ibukiense Toy.、短丛木灵藓O.pumilum Sw.和卷叶木灵藓O.revolutum C.Muell.为新疆新记录种。通过对新疆新记录种的生境、识别特征、采集地点、地理分布、海拔等信息的整理分析,绘制了4个种的线条图,并编制了新疆木灵藓属植物的分亚属和分种检索表。

英文摘要：

In views of the advance of research on the genus Orthotrichum and according to the specimens of 350 packets collected from different parts of Xinjiang, 17 species are reported in this paper. Among them 1 species （ O. alpestre Hornsch. ex B. S. G. ） is reported for the first time in China, and 4 species （ O. hookeri Wils. ex Mitt. , O. ibukiense Toy. , O. pumilum Sw. and O. revolutum C. Muell. ） are reported for the first time in Xinjiang. All species are in 5 subgenera,6 species （ O. affine Schrad. ex Brid. , O. dasymitrium Lewinsky in T. Kop. , O. hookeri Wils. ex Mitt. , O. sordidum Sull. et Lesq. , O. speciosum Nees. and O. striatum Hedw. ） in subg. Gymnoporus, 1 species （ O. obtusifolium Brid. ） in subg. Orthophyllum ,5 species （ O. alpestre Hornsch. ex B. S. G. , O. crenulatum Mitt. , O. pallens Bruch. ex Brid. , O. pumilum Sw. and O. revolutum C. Muell. ） in subg. Pulchella, 1 species （ O. rupestre Schleicher ex Schwaegr. ） in subg. Phaneroporum, and 4 species （ O. anomalum Hedw. , O. cupulatum Brid. , O. hallii Sull. et Lesq. and O. ibukiense Toy. ） in subg. Orthotrichum. According to these specimens, the keys to the subgenera and species are made respectively. The Chinese names, Latin names and reference literatures as well as the characteristics and geographical distribution of the species are also included. The purpose is to provide the data for the compilation of Flora Bryophytarum in Xinjiang. The studied specimens are deposited in the herbarium of College of Life Science and Tecnology,Xinjiang University （XJU） and the Institue of Botany,Chinese Academy of Sciences.
