Galanthus subalpinus (Amaryllidaceae): a new species of snowdrop from the Western Balkans

Summary Galanthus subalpinus (Amaryllidaceae), a new snowdrop species endemic to the Western Balkans (North Macedonia and Kosovo) is described and illustrated. Morphological differences between the new species and the similar Galanthus species, G. nivalis and G. graecus , are reported and discussed, in combination with DNA sequence data from plastid ( trn L- trn F, mat K) and nuclear (ribosomal ITS) markers and genome size. Line drawings, photographs of habitat and morphology, a distribution map and a preliminary conservation assessment are provided. The genome size (1C-value) of G. bursanus , G. samothracicus and G. × valentinei nothosubsp. subplicatus are reported for the first time .
