Allium ulleungense (subg. Anguinum, Amaryllidaceae), from Ulleungdo Island, Korea, is described as a new species. It is clearly distinguished from its close relatives, A. microdictyon and A. ochotense, by its broader leaves and larger whitish perianth and by its diploid chromosome number, which is 2n = 2x = 16. The lengths of the chromosomes range from 11.3 to 15.75 ㎛. Molecular phylogenetic analyses using nuclear and chloroplast markers also clearly indicate that A. ulleungense is genetically distinct from other species of the subg. Anguinum.
