Abstract

The microstructural characteristics of the vegetative and generating organs of the medicinal plant Allium saxatile Bieb. has been studied, using Carl Zeiss, Jeneval light microscope and Omax stereoscopic microscope. The leaves of A. saxatile are bare and have toothed edge. Mesophyll of the leave is characterized with an isolateral structure. leaf-covering tissue is sharply cutinized, the cell membrane of the single-rowed epidermal tissue is strongly thickened. Stem is bare, the protective tissue is actively cutinized, the epidermis is in a single layer, its cells are characterized by a square shape and have a strong thickening of the outer periclinary walls. The vascular bundle is represented with a group layout of lumens of large and small-caliber conductive vessels of an oval and weakly angular shape.  The thickening of the shell of the vascular bundle is predominantly spiral. Inflorescence is round, with a frequent flower umbrella. The perianth is egg-bellish, its cover is free, elongated, pointed shape, pale pink in color. Filaments are longer than flowers of the perianth. Bulb is free, surrounded by an elongated-conical shape, brownish coloring, dried, leathery shell. The root of have shape of sphere, covering tissue of root – exoderm have double row of cells and is represented with thin-skinned smaller size and large, square-shaped cells.
