摘要:

自小美喙藓属(Eurhynchiastrum Ignatov & Huttunen)2002年建立以来,中国有关该属系统的分类学研究尚未开展。笔者对中国小美喙藓属相关标本和文献进行了研究,结果表明:中国分布小美喙藓属植物1种,即小美喙藓(E. pulchellum(Hedw.) Ignatov & Huttunen),对其形态特征、生境及地理分布进行了描述和记录,提供了主要形态特征图版,与形态相近属和种进行了分析比较,并对其在中国的潜在地理分布区进行了预测。

Abstract:

Since its establishment in 2002, no taxonomic study on the genus Eurhynchiastrum Ignatov & Huttunen has been carried out in China. Based on the related specimens and literatures, the authors conducted an investigation on the genus in China. The results showed that the genus was distributed in China with a single species, E.pulchellum(Hedw.) Ignatov & Huttunen. The morphological characters, habitats and geographical distribution of the species were described. Additionally, a plate illustrating the main morphological features was provided, and a discussion on the comparison among allied genera and species was included. Furthermore, the potential geographic distribution of E.pulchellum in China was predicted.

Key words: Eurhynchiastrum pulchellum, Eurhynchium, Eurhynchium angustirete, China, potential geographical distribution
