报道和描述了花叶藓科 (Calymperaceae) 和平藓科 (Neckeraceae) 在中国的两个新分布属:脆尖藓属 (新拟名) (Arthrocormus Dozy & Molk. ) 和卷枝藓属 (新拟名) (Noguchiodendron TN. Ninh & Pócs)。脆尖藓 (Aschimperi) 和球蒴卷枝藓 (Nsphaerocarpum) 分别为这两个单种属的模式种,前者在热带亚洲及大洋洲地区具有较广的分布,后者目前仅报道于不丹、印度、尼泊尔和泰国。这两种苔藓植物之所以被采集者忽略的主要原因在于它们同一些常见种在外形上的高度相似。呈圆锥状且极易破碎的叶尖是脆尖藓区别于其他藓类的重要特征,而干燥状态下营养枝末端强烈卷曲是卷枝藓属最显著的鉴别特征。

Two monotypic genera, Arthrocormus Dozy & Molk. and Noguchiodendron TN. Ninh & Pócs are reported as new distributional records for China. Arthrocormus schimperi is widely distributed in tropical Asia and Oceania, while Nsphaerocarpum is previously reported from Bhutan, India, Nepal and Thailand. Arthrocormus schimperi looks like some Leucobryaceae species and Nsphaerocarpum resembles Homaliodendron spp. We speculate these are the main reasons why they have been overlooked by collectors. The extremely brittle tips with a cylindrical appearance in the upper portion of leaves make Arthrocormus very distinguishable in the field, while the strongly curled branch in dry condition is the most diagnostic feature of Noguchiodendron. Illustrations for both taxa reported are provided for reference purposes.
