Microstructural features of generative and vegetative organs of Allium saxatile growing in Georgia

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 a toothed edge. Mesophyll of the leave is characterized by an isolateral structure. leaf-covering tissue is sharply cutinized, and the cell membrane of the single-rowed epidermal tissue is strongly thickened. The stem is bare, the protective tissue is actively cutinized, the epidermis is in a single layer, and its cells are characterized by a square shape and have a strong thickening of the outer periclinal 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. The inflorescence is round, with a frequent flower umbrella. The perianth is egg-bellish, its cover is free, elongated, pointed in shape, and pale pink in color. Filaments are longer than flowers of the perianth. The bulb is free, surrounded by an elongated-conical shape, brownish coloring, and dried, leathery shell. The root of have the shape of a sphere, covering the tissue of the root – exoderm has a double row of cells and is represented by thin-skinned smaller size and large, square-shaped cells.
