Especies del grupo Intravaginal de Festuca L. sección Festuca en los pisos basal y montano del nordeste de la Península Ibérica

Fescues of the Intravaginal group of Festuca L. section Festuca in the lowland and montane areas of the northeastern Iberian Peninsula.— Morphologically similar fescues occur across the study area (Mediterranean area of the northeastern Iberian Peninsula) at low and middle elevations. With the exception of the high mountain or alpine species, these populations are reviewed here, with particular attention being paid to the Festuca inops (F. gracilior) group, as well as to some other species, in particular F. lemanii, which are not easily understood and can complicate identification, especially where the taxa occur sympatrically. The application of the binomen F. inops De Not. to some of the Iberian populations constituting the F. inops group is discussed. New records for F. tarraconensis, F. occitanica, F. michaelis and F. heteroidea amplify the distribution range of these little-known taxa within the Iberian Peninsula.
