Taxonomic revision of the Erigeronacris group (Asteraceae) in Murmansk Region, Russia, reveals a complex pattern of native and alien taxa.

ABSTRACT: Based on the evidence of morphology and a comprehensive revision of herbarium collections and field records, the taxonomy of the Erigeronacris group in Murmansk Region, European Russia, is completely revised. Its accepted diversity is increased from 2 to 8 taxa, including putative hybrids. The only native species, E.politus, is distributed in mountainous regions, along sea coasts and in the Kutsa River basin. Five species are alien: E.rigidus (previously confused with E.acris s.str.), E.acris s.str.
