Kurzfassung:
Allium section Rhizirideum is reviewed for South Korea and neighboring northeastern China based on critical observation of wild populations and herbarium materials. Species delimitations are re-evaluated on the basis of morphological and somatic chromosome numbers, resulting in the recognition of five species. Allium dumebuchum from Ulleungdo Island, South Korea, is described as a new species. This species is most similar to A. senescens due to its habits, but is clearly distinguished particularly by its rhomboid scapes in cross-secion, light purple perianth color, entire and narrowly triangular inner filaments, and flowering season from late September. One previously recognized species is placed into synonymy: A. pseudosenescens (under A. senescens ). Photographs and a key to species of Allium section Rhizirideum in South Korea and northeastern China are provided in addition to information on nomenclatural types, synonymies, chromosome numbers, distribution, and specimens examined.
