    摘要:

    【目的】了解歧舌苔属植物在广西的实际分布情况,为广西苔藓植物研究增加新资料的同时,也为中国苔藓植物多样性保护添加必要的基础数据。【方法】通过近期的野外调查结合广西植物标本馆(IBK)馆藏标本的核查,获得歧舌苔属植物研究材料,经室内形态观察及查阅相关文献,确定其物种多样性。【结果】发现广西歧舌苔属植物标本10份,最终确认广西歧舌苔属植物3种,分别为毛缘歧舌苔,大歧舌苔、阔叶歧舌苔。【结论】歧舌苔科以及岐舌苔属均为首次在广西记录的科属,其中毛缘歧舌苔是中国新记录种。文章对毛缘歧舌苔的形态特征进行了详细描述,对另外2个种主要形态特征进行了归纳,并提供各个种的引证标本信息、地理分布以及彩色图版。

    Abstract:

    [Objective] The study aimed to understand the actual distribution of the species of Schistochila in Guangxi, should not only add new data for the study of bryophytes in Guangxi, but also add necessary basic data for the protection of bryophyte diversity in China. [Methods] Through the recent field survey and checking specimens of Schistochila from Guangxi Herbarium (IBK), the species diversity were determined by morphological observation and relevant literature review. [Results] Ten specimens of Schistochila from Guangxi were found, and three species of Schistochila in Guangxi were finally confirmed, namely, Schistochila aligera (Nees & Blume) J.B. Jack & Steph., S. blumei (Nees) Trevis. and S. sciurea (Nees) Schiffn. [Conclusion] Schistochilaceae and Schistochila were here reported as new records to Guangxi at the levels of family and genus, respectively. Here, Schistochila sciurea was firstly reported to bryoflora of China. Detailed description of Schistochila sciurea and main diagnostic characters of S. aligera and S. blumei were provided based on the studied specimens. Each species was also accompanied by vouchers, distribution information and a color plate.
