The Asian genus Ajania Poljakov comprises about 30-40 species. Because of its complex taxonomic history with numerous movements of species between the two main groups of Artemisiinae Less., Ajania and individual genera are a particularly interesting group to study. Ajania cover most of the entire distribution range in Central Asia, with most in China, Korea, Japan and the Far East. The purpose of this research work is to clarify the morphological features of Ajania fastigiata (C. Winkl.) Poljakov, diagnostic features of vegetative organs of medicinal plants, which improves the quality of selection of raw materials for use in pharmacology. The material for the study was collected in September 2022. Morphometric data and macro-images were taken using a Levenhuk DTX RC3 remote-controlled microscope. The morphometric features were measured using “ImageJ” software The basic features were based on data from “Flora of Kazakhstan” and ‘Central Asian Explorer”. As a result of analysis of morphometric data Ajania fastigiata for Trans-Ili Alatau determined diagnostic features of vegetative organs of medicinal plants, which can improve the quality of selection of raw materials for use in pharmacology: height from 30 to 110 cm, but in most cases 50-80 cm; stem in the middle part 1.3-1.5 mm; width of septate leaves 0.7-1.0 mm; diameter of the basket 3.5-3.7 mm, stem of the basket 0.6-0.7 mm; diameter of the lower part of the tubular flower 0.5 mm, upper part 0.7 mm.
