For the first time, the morphological and anatomical structures of the leaves of different age individuals of the medicinal and rare species F. tadshikorum were studied in Tashkent Botanical Garden. Currently, natural populations of the species are in decline, and for the preservation and production of medicinal raw materials, research on the ex situ development conditions is needed. According to the results, adaptive responses to new habitat conditions in the anatomical structures of the vegetative organs were found. Plants of juvenile and immature development stages retained the the mesophyll's isolateral-palisade type, but differed in other quantitative and qualitative indicators of leaf tissues. Immature plants of the second year of life with more developed leaves showed modifications in the anatomical structure of the leaves, with powerfully developed vascular bundles, mechanical tissue, secretory ducts, as well as the presence of deep fibers both above the phloem of peripheral bundles, and also above the phloem of the central bundles of the petiole.
