Anatomical structure of some dying plants of the Lesser Caucasus

The article provides information about the morpho-anatomical and coloring properties of some plants of the Lesser Caucasus, common in the territory of Azerbaijan. The distribution zones of species are indicated, anatomical studies are carried out, and both permanent and diagnostic structural indicators of taxa are determined. It was found that plants in the mountain zone develop characteristic features: thickening of the leaf blade; strong development of palisade parenchyma; a decrease in the volume of stomata, but an increase in their number; thickening of the membrane and cuticle of epidermal cells, formation of dense hair; reduction and compaction of cells.
