Stipa adamii M. Nobis sp. nov. (Poaceae), endemic to Kazakhstan, is described and illustrated. The species belongs to the section Smirnovia Tzvel. and is distributed in the central Karatau Mountains (western Tian-Shan). It is morphologically close to Stipa karataviensis Roshev. but is easily distinguishable by longer glumes, lemmas, awns and the callus. The awn is scabrous in the lower part and the callus is bearded in S. adamii whereas both organs are glabrous in S. karataviensis. Characters distinguishing S. karataviensis and S. adamii are presented in a table, together with photographs of the callus. The analysis of morphological characters of the taxa provides new information on their variability. A key to the species of Stipa sect. Smirnovia occurring in Kazakhstan, typification of the name S. manrakica and synonymization of the name S. saurica as a syn. nov. are included.
