A new species of Agrostis L. (A. barceloi ) is described from the northern mountains of Mallorca (Balearic Islands). The new taxon belongs to sect. Agtush and is mainly related to A. alpina Scop. and A. schleicheri Jord. & Verl. on morphological grounds. However, A. barceloi differs from A. alpina by its narrowly‐lanceolate inflorescence, with panicle branches erect during and after anthesis, non‐scabrid leaves, and by smaller lemmas and others. The new species is distinguished from A. schleicheri by the smaller spikelets, lemma, palea, and anthers. In addition, A. barceloi is tetraploid (2n = 28), and differs cytologically from the diploid A. alpina (2n= 14) and the hexaploid A. schleicheri (2n = 56).
