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.
