The hepatic flora of Tardoki-Yani Mts., a subordinate range in the northern part of Sikhote-Alin mountain system, was studied and analyzed. In total, 106 species were found, 24 of them are new for Sikhote-Alin. The flora is a mixture of temperate East Asian and circumpolar arctic-alpine taxa, the fact corresponding the geographic position of Tardoki-Yani Mts. at the boundary between East-Asian and Circumboreal floristic provinces, as well as the wide range of elevations, from 500 to 2090 m, the latter being the highest point of Sikhote-Alin. Many arctic-alpine taxa occur in Tardoki-Yani in considerable isolation from the nearest localities in  northern Asia and are the southernmost in the world. The latter, as well as wide distribution of late glacial landscapes in the studied area allow us to consider Tardoki-Yani as the largest southern refugium of arctic-alpine hepatic flora in East Asia.
