摘　　要：报道了产自西藏墨脱的中国悬藓属新记录种——多齿悬藓(Barbella horridula Broth.)。多齿悬藓曾报道产于印度尼西亚(苏门答腊岛)和菲律宾(吕宋岛),经与模式标本比较,该标本仅在叶中部细胞和角细胞的分化程度上与模式标本略有不同。该种的茎叶为狭卵状披针形,叶中部细胞较长及边缘具明显的齿,可与同属国内其它种相区别。该文对多齿悬藓的形态特征进行了详细描述并提供了显微形态照片,编制了中国悬藓属植物分种检索表。Barbella horridula Broth.,previously reported from Indonesia(Sumatra)and the Philippines(Luzon),is now reported as a new addition to China based on a specimen collected from Medog,Tibet.The Chinese plant exhibits minor differences when compared with the type specimen,i.e.,relatively longer laminal cells and slightly differentiated alar cells.It can be distinguished from other members within the genus in China by the narrowly ovate lanceolate stem leaf,longer laminal cells in the middle,and margins distinctly serrulate.In addition to a detailed description and microscopic illustrations of B.horridula,a key for all Chinese species in the genus is also provided.
