Abstract
A new species, Alliumsunhangiisp. nov., of the Middle Asiatic section Brevidentia F.O.Khass. & Iengal., (subgenusAllium, tribe Allioideae, Amaryllidaceae) is described. The species is a small plant from the Babatag Ridge in the Surkhandarya province of Uzbekistan. It is morphologically close to Alliumbrevidens Vved. in having initially dark violet filaments and three-cuspidate inner filaments, but differs by its small size and visibly unequal tepals as well as in the phylogenetic analysis based on ITS data.
