Allium formosum Sennikov & Lazkov sp. nov. is described as new to science and illustrated. This species is the second member of A. sect. Spathulata F.O.Khass. & R.M.Fritsch, being different from A. spathulatum F.O.Khass. & R.M.Fritsch in larger, broader, obtuse and more intensely purple-coloured tepals, and in a more robust habit. It is a local endemic of Babash-Ata Mt. Range situated east of Fergana Valley in Kyrgyzstan, recommended for legal protection as Endangered because of the very small population size in its only locality.
