摘      要：The article presents the results of research carried out by light microscopy of the anatomical structure of vegetative organs (leaf, root and stem) Lavandula officinalis Chaix of the family Lamiaceae introduced into the conditions of the Tashkent Botanical Garden of the Republic of Uzbekistan. Our studies have shown that the presence or absence of trichomes can serve as an informative sign. In L. officinalis trichomes are simple unicellular two-terminal;three-terminal and multi-terminal. Lavender leaf hairs accumulate essential oils under the cuticle of secreting cells, the cuticle are tightly attached to the membranes of the secretory cells due to the absence of excretion products. Based on the results of a study of the morphological and anatomical features of the leaf of L. officinalis, it has been established that the forms of covering hairs and essential oil glands are of diagnostic value. In the epidermal, palisade and cortex parenchymal cells of the vegetative organs, yellow-orange essential (lavender) oil is noted. Identified diagnostic features that can be used in taxonomy and can be used to identify plant materials can also be used to develop indicators of authenticity in this type of raw material.
