Аннотация
Abstract The alliances of Allium filidens Regel and A. brevidens Vved. were taxonomically revised. Three subspecies were recognized for A. filidens . The widely distributed typical subspecies is characterized by thick reticulate bulb tunics, relatively short leaf sheathes, and whitish tepals with greenish or bluish median veins. Subspecies ugamicum (Vved.) R.M.Fritsch & F.O.Khass. occurring in Chatkal, Pskem, and Ugam mountain ranges E and NE of Tashkent, has delicate, reticulate bulb tunics, relatively longer leaf sheathes, and faintly blue to violet flowers. Subspecies mogianense R.M.Fritsch & F.O.Khass. occupies a small area of distribution in western Hissar mountain range and differs from subsp. ugamicum by greenish tepals with broad green median veins. A key for determination of these subspecies is given. Allium brevidens subsp. pshikharvium R.M.Fritsch & F.O.Khass. was newly described from higher altitudes of Tajik Vanch, Darvaz, and Peter I. mountain ranges. It differs from the typical subspecies by larger scapes, denser inflorescences, green (not yellowish) tepals with dark‐green median veins and violet (not purplish) filaments.
