The genus Leskea
in Russia is represented by one widespread species, L. polycarpa Hedw. Records of
L. gracilescens appeared
to be erroneous.
Analysis of nuclear ITS sequence
data demonstrated that North American
samples of L. gracilescens and L. obscura clearly differ from European
and Asian populations in several characteristic substitutions. Anomalous morphology of plants
from Yakutia and Amur Province
is described and illustrated. Their distribution likely corresponds to a high
and late floodings of big
rivers, crossing permafrost areas.
