Morphometrics and taxonomy of Erigeron acris sensu lato
Morphometric multivariate analysis has been performed based on 23 characters observed on 113 herbariumspecimens from throughout Fennoscandia. This demonstrates that four taxa can be recognised withinErigeron acris L. sensu lato, viz. E. acris L. subsp. acris, E. acris subsp. decoloratus (H. Lindb.)...
