During the revision of specimens of the taxon, we observed that the pattern of this variability is linked to the geographical distribution of the specimens. Numerical analyses (PCA and UPGMA) revealed three groups of OTUs corresponding to three morphotypes within the <em>S. purpurea<\/em> complex. A set of macro- and micromorphological characters, supported by a map of general distributional ranges, are presented to distinguish each of the three taxa within the complex and we reassess the status of Lasiagrostis tremula described by Ruprecht in 1869. As a result, <em>Stipa tremula<\/em>, <em>S. purpurea<\/em> and <em>S. arenosa<\/em> were distinguished within the complex. The intermediate characters of S. arenosa may suggest its putative hybrid origin (<em>S. tremula \u00d7 S<\/em>. <em>purpurea<\/em>), while the presence of extremely long florets may be an expression of the gigas effect. We propose two new combinations (<em>S. tremula<\/em> and <em>S. arenosa<\/em>), describe a new nothospecies (<em>S. \u00d7ladakhensis<\/em>) that originated from hybridization between S. klimesii and S. <em>purpurea<\/em> s.l. and designate the lectotype for <em>Ptilagrostis semenovii<\/em>.
