摘要 | 对西南岩溶国家公园候选区苔藓植物物种多样性进行考察，通过标本鉴定和文献查阅，确定广西藓类植物新记录7种，分别为暖地高领藓〔Glyphomitrium calycinum (Mitt.) Cardot〕、短枝高领藓〔Glyphomitrium humillimum (Mitt.) Cardot〕、美丽拟同叶藓〔Isopterygiopsis pulchella (Hedw.) Z. Iwats.〕、陈氏藓〔Chenia leptophylla (Müll. Hal.) R. H. Zander〕、仰叶藓〔Reimersia inconspicua (Griff.) P. C. Chen〕、刺藓〔Rhachithecium perpusillum (Thwaites et Mitt.) Broth.〕和短齿藓〔Brachydontium trichodes (F. Weber) Milde〕，分属于6个广西新记录属，分别为高领藓属（Glyphomitrium Brid.）、拟同叶藓属（Isopterygiopsis Z. Iwats.）、陈氏藓属（Chenia R. H. Zander）、仰叶藓属（Reimersia P. C. Chen）、刺藓属（Rhachithecium Broth. ex Le Jol.）以及短齿藓属（Brachydontium Fürnr.）。此外，刺藓科（Rhachitheciaceae）为广西新记录科。这些发现进一步丰富广西藓类植物科、属多样性。

Abstract | An investigation of bryophyte species diversity was conducted in the proposed Southwest Karst National Park. Through specimen identification and literature review, seven moss species are confirmed as new records in Guangxi, including Glyphomitrium calycinum (Mitt.) Cardot, Glyphomitrium humillimum (Mitt.) Cardot, Isopterygiopsis pulchella (Hedw.) Z. Iwats., Chenia leptophylla (Müll. Hal.) R. H. Zander, Reimersia inconspicua (Griff.) P. C. Chen, Rhachithecium perpusillum (Thwaites et Mitt.) Broth., and Brachydontium trichodes (F. Weber) Milde. These species belong to six newly recorded genera in Guangxi, including Glyphomitrium Brid., Isopterygiopsis Z. Iwats., Chenia R. H. Zander, Reimersia P. C. Chen, Rhachithecium Broth. ex Le Jol., and Brachydontium Fürnr. Moreover, Rhachitheciaceae is a newly recorded family in Guangxi. These findings further enrich the diversity of moss families and genera in Guangxi.
