摘要:

该文在对中国西藏色季拉山苔藓植物野外采集和鉴定的基础上,报道了西藏合叶苔属新资料。结果表明:合叶苔属植物共有13种,其中西藏新记录种2种,即厚边合叶苔(Scapania carinthiaca J.B. Jack)和东亚合叶苔(S. orientalis Steph. ex K. Müller); 此外,还有色季拉山新记录种9种,分别为多胞合叶苔(S. apiculata Spruce)、刺边合叶苔(S. ciliata Sande Lac.)、短合叶苔[S. curta(Mart)Dumort.]、长尖合叶苔[S. glaucocephala(Taylor)Austin]、林地合叶苔[S. nemorea(L.)Grolle]、尼泊尔合叶苔(S. nepalensis Nees)、小合叶苔(S. parvifolia Warnst.)、弯瓣合叶苔(S. parvitexta Steph.)、粗疣合叶苔(S. verrucosa Heeg.)。同时,还对其中厚边合叶苔、东亚合叶苔和长尖合叶苔的形态特征和地理分布进行了描述,并提供了主要形态特征的照片。凭证标本存放于中国农业大学标本室(BAU)中。

Abstract:

Based on the field investigation and specimen identification of bryophytes of Sygara Mountain in Tibet Autonomous Region, thirteen species of genus Scapania (Hepaticae, Scapaniaceae)were reported. Two species(S. carinthiaca J. B. Jack and S. orientalis Steph. ex K. Müller.)are newly recorded in Tibet Autonomous Regionare. In addition to the two species mentioned above, there are nine species including S. apiculata Spruce, S. ciliata Sande Lac., S. curta(Mart.)Dumort., S. glaucocephala(Taylor)Austin, S. nemorea(L.)Grolle, S. nepalensis Nees, S. parvifolia Warnst, S. parvitexta Steph. and S. verrucosa Heeg. are newly recorded in Sygara Mountain of Tibet. The morphological characters and geographical distribution of S. carinthiaca, S. orientalis and S. glaucocephala are described, and the primary morphological characters photos are provided. The results provide new information for Scapania in China and bryoflora of Tibet. The voucher specimens are preserved in the herbarium of China Agricultural University(BAU).
