(Poaceae), endemic to the Azores archipelago (Portugal), is described. The vegetative and reproductive structures were studied. The diagnostic characters were compared with those of closely related species. New chromosome counts in Holcus azoricus M. Seq. & Castrov. (2n = 35) and H. rigidus Hochst. (2n = 28) are included. A possible hybrid origin is hypothesized; the potential parents are H. lanatus L. and H. rigidus.engHolcus rigidusHolcus lanatusHybridsGramineaeAzores (Portugal)Açores (Portugal).Faculdade de Ciências da Vidajournal article10.1111/j.1095-8339.2007.00652.x
