ABSTRACT. Moss flora of the Orulgan Mountain Range in Yakutia is studied on the material of the expedition of 2011, which crossed the Range at 67–68° North. The area comprises northern taiga combined with tundro-steppe areas and mountain tundra vegetation. 241 moss species are revealed including some rare xerophytes, Indusiella thianschanica, Entosthodon pulchellus, Bryoerythrophyllum latinervium, and Didymodon johansenii. Other rare and interesting findings include Orthotrichum holmenii, Meesia hexasticha  and Lyellia aspera. However, many arctic species which had been expected to be found were not collected. Regardless of the moderate overall diversity, the area is interesting in a prevailing specific mire type with Scorpidium scorpioides as a dominant, and at places nearly the only moss species.
