Th. article presents th. results of studies of th. anatomical structure of th. vegetative organs of Allium kysylkumi of the Amaryllidaceae family, which grows in the conditions of Kyzylkum (Kokchatau outlier mountain). The characteristic diagnostic features have been determined: the outer membrane of epidermal cells is well developed by the outer folded cuticle, cutinized and more thickened;leaves are amphistomatic;stomata are the most submerged, anomocytic type;isolateral-palisade type of leaf mesophyll;the conducting bundles are closed, collateral and are arranged in two rows, of which the upper side is represented only by small bundles, in the lower row, 3 large bundles alternate with one small bundle;peduncle and peduncle, parenchymal-beam type of structure;the epidermis is single-row, folded cuticle with more thickened and cutinized;the crustal parenchyma is thin-walled, round-oval, chlorophyll-bearing;the presence of lactic acid is in the cow parenchyma;the primary cortex is separated from the central cylinder by a ring of sclerenchyma;the central cylinder is extensive;closed collateral-type conductive bundles. In the vegetative organs of Allium kysylkumi, especially in the leaf, xeromorphic characters are pronounced, which indicates the fitness of this species in natural habitat. The revealed structural diagnostic signs of vegetative organs are species-specific, and sh.w th. adaptation of th.s species t

Central Asia is one of th. main centers of origin of bulbous geoph.tes, including th. family Amaryllidaceae Juss. Th. anatomical features of many endemic, red-book bulbous geoph.tes are still poorly understood. Th. article presents th. results of a structural study of th. inflated part of th. stem (fistular), stem and pedicels of an endemic A. praemixtum species grow in two different environmental conditions in th. Aktau mountain Nurata Range (Uzbekistan, Province Navoi) and in th. conditions of introduction in th. Tash.ent Botanical Garden (Uzbekistan, Tash.ent city). Diagnostic signs of vegetative organs were revealed and various combinations of xeromorph.c and mesomorph.c signs were determined. Comparative anatomical study of vegetative organs of A. praemixtum is of great th.oretical and practical importance in relation to taxonomy and ecology.
