ABSTRACT

The results of a study conducted by light microscopy methods of the anatomical structure of the vegetative organs of Spiraea hypericifolia growing in natural habitat in the Bakhmal district in the south of the Jizzakh region of Uzbekistan are presented and the following diagnostic features are identified: in the leaf—isolateral-palisade type of mesophyll leaf; thick-walled outer walls of the epidermis; amphystomatic leaves; not submerged stomata; chlorophyll-bearing palisade and spongy parenchyma; open collateral type of vascular bundles and sclerified, due to collenchymal cells; in the stem and root—the beam type of structure and more lignified; the stem and root are divided into three topographic zones: the periderm (cork), the secondary cortex and the central cylinder; the periderm is represented by a cork and its cells are dark brown, thick-walled, tightly closed; groups of bast fibers are formed under the cow parenchyma; extensive librimiform; core and radial rays elongated and short; the phloem is extensive, located between the cortex parenchyma and libriform; the narrow core is represented by large and small, round-oval, thin-walled parenchymal cells and they contain hydrocytic cells. Diagnostic signs revealed by us reflect more xeromorphic of this species. All traits were compared, and we concluded that the anatomical traits of the leaf, stem, and root may be useful in providing diagnostic traits for distinguishing the taxa studied.
