Morphological variation in Scandinavian populations of the diploid-tetraploid species pair Anthericum ramosum and Anthericum liliago (Anthericaceae)
Both members of the diploid-tetraploid species pair Anthericum ramosum L. and Anthericum liliago L. occur as geographically disjunct isolates on the margins of their northern range in Scandinavia. Variation in floral morphology was studied in 33 populations of A. ramosum from four geographic regions and 25 populations of A. liliago from seven regions in Scandinavia. Tepal shape was characterized w
