A survey of the moss flora of the southernmost part of the Russian Primorsky Territory yielded several intriguing taxa, whose identity is assessed herein based on an integrative morpho-molecular approach. was previously known in inland Asia only from the Sino-Himalayan region and the new locality is distant from the earlier known ones to ca. 3000 km. Despite the morphological uniformity, Russian specimens are remarkably distinct in sequences of all three obtained DNA markers, approaching an American specimen in the sequence. Another probable relic, cf. , appeared to be fairly common in the southern part of the Primorsky Territory, where low mountains are covered with hard-leaved forests. Russian specimens of cf. var. show significant divergence from s.str., which also has complex phylogenetic structure, obscuring further taxonomic implications. The description and illustrations of both taxa based on Russian specimens are provided, and the area, where both species occur, is briefly characterized; it includes numerous thermophilous species, which are rare or do not occur northwards. Our case study uncovers the problem of cryptic speciation within species distributed in temperate climate and is considered to represent relics of Arcto-Tertiary flora.
对俄罗斯滨海边疆区最南端苔藓植物区系的一项调查发现了几个有趣的分类群，本文基于综合形态分子方法对其进行了鉴定。此前在内陆亚洲仅在中喜马拉雅地区发现过该物种，而新发现的地点距离此前已知地点约3000公里。尽管形态上具有一致性，但俄罗斯标本在所有三个获得的DNA标记序列上都明显不同，在 序列上接近一个美国标本。另一个可能的残遗种，cf. ，在滨海边疆区南部似乎相当常见，那里的低山被硬叶林覆盖。俄罗斯的cf. 变种标本与s.str. 表现出显著差异，s.str. 也具有复杂的系统发育结构，这使得进一步的分类学意义变得模糊。文中提供了基于俄罗斯标本对这两个分类群的描述和图示，并简要描述了这两个物种出现的区域；该区域包括许多喜温物种，这些物种在北方很少见或不存在。我们的案例研究揭示了分布在温带气候中的物种内隐存物种形成的问题，并被认为代表了北极第三纪植物区系的残遗种。
