Resumen
- A taxonomidal revision of the genus Festuca sect. Eskia in the Iberian Peninsula is presented. Seven species and two hybrid taxa are recognized in this section in the area studied. Karyological data show that six of the studied taxa (F. pseudeskia, F. scariosa, F. elegans subsp, elegans, F. burnatff, F. eskia, and F. xpicoeuropeana) are diploids, two of them are both diploid and tetraploid (F. gautieri and F. quadriflora), one is tetraploid (F. elegans subsp, merinoO and the ploidy level of one taxon (F. xsouliei) is unknown. A new combination F. elegans subsp, merinoi (PAU) FUENTE et ORI"0N~Z is published. A key based on data collected in this study allows for the identification of all taxa in this section. The complete description of each taxon is presented, as well as the ecology and chorology, including distribution maps. The illustrations summarize plant habits and the morphological and anatomical pattern observed on spikelets, ligules and leaf cross sections.
  
  Epidermal features were studied using scanning electron microscopy.
