33B1FC436CF25B81AFB3A0D18D3ABDC7.taxon	diagnosis	Diagnosis. This new species is morphologically similar to A. senescens due to its habits. However, it is clearly distinguished from A. senescens, particularly by its rhomboid scapes in cross-secion (vs. subterete), light purple perianth color (vs. pale purple), entire and narrowly triangular inner filaments (vs. sometimes toothed and broadened for ca. 1 / 2 in length), and flowering season from late September (vs. from July).	en	Jang, Ju Eun, Park, Jong-Soo, Jung, Ji-Young, Kim, Dong-Kap, Yang, Sungyu, Choi, Hyeok Jae (2021): Notes on Allium section Rhizirideum (Amaryllidaceae) in South Korea and northeastern China: with a new species from Ulleungdo Island.
