Achillea millefolium complex, Anthemideae, chorology, eastern Pyrenees, ecology, nomenclatureAbstract
The status of the species and a subsequent nomenclatural combination are proposed for Achillea ceretanica, a diploid taxon endemic of eastern Pyrenees included in the A. millefolium complex. Synonymisation of A. monticola Martrin-Donos with A. ceretanica is refuted, given that the first is a clearly distinct octoploid lineage of the complex. Some comments on distribution, ecology and frequency of both are added.
