New and rare plant species for the Polar Urals

Abstract

The article contains data on localities of new and rare species and subspecies of vascular plants for the Polar Urals. The general distribution of Betula concinna is only approximately known. Botrychium alaskense is recorded in Western Siberia only in Altai. Crepis paludosa is lost in the Siberian flora. For 5 species and 1 subspecies (Alchemilla glomerulans, Astragalus gorodkovii, Botrychium boreale, B. lunaria, Castilleja arctica subsp. vorkutensis, Cystopteris fragilis) new localities were noted, confirming their occurrence or clarifying their distribution in the Polar Urals.
