Bryophyte flora of Hunan Province, China. II. Orthotrichaceae (Musci)

摘要

The moss flora of Hunan Province, China, has seven genera and 17 species in the family Orthotrichaceae. Zygodon rupestris Schimp. ex Lor. is new to China. New records for Hunan include the genera Schlotheimia and Zygodon, and Macromitrium syntrichophyllum Ther. & P. de la Varde, M. ferriei Card. & Ther., Orthotrichum rupestre Schleich. ex Schwaegr., O. exiguum Sull., O. subpumilum Bartr. ex Lewinsky, and Schlotheimia grevilleana Mitt. Ulota macrocarpa Broth. is synonymized with U. crispa (Hedw.) Brid. and Macromitrium quercicola Broth. with M. ferriei. A new name Schlotheimia vittii Guo, Enroth & T.J. Kop. is proposed for S. rubiginosa (Mull. Hal.) D.H. Vitt, hom. illeg. Eight lectotypes are selected or corrected (indexed). All species but M. ferriei are rare or very rare in Hunan. They are mostly epiphytic growing on trunks and branches of trees. They can survive in disturbed and man-made habitats, if suitable phorophytes are available. The species are described and most of them are illustrated in line drawings, and their altitudinal ranges in Hunan are presented in diagrams.
