Based on numerical analyses of macromorphological characters (cluster analysis, principal coordinate analysis and principal component analysis), scanning electron microscopy observation of lemma and lamina micromorphology, as well as field observations, five taxa belonging to theStipa turkestanicagroup have been recognized in the mountain area of Central Asia. They areS. turkestanicasubsp.turkestanica,S. turkestanicasubsp.trichoides,S. macroglossasubsp.macroglossa,S. macroglossasubsp.kazachstanicaandS. kirghisorum. As a result of this study, we propose one new combination,S. macroglossavar.pubescens, and designate lectotypes forS. turkestanicasubsp.trichoidesandS. macroglossavar.pubescens, and an epitype forS. kirghisorum. Illustrations of micromorphological structures of the lemma, patterns of leaf hairiness and an identification key are provided. A taxonomic synopsis including information on nomenclatural types, synonyms, descriptions of the taxa, and, as supplementary information, a list of the specimens examined is also presented.
