• Resumen

  • The species Festuca valesiaca, F. rupicola, F. galiciensis, F. macutrensis (F. valesiaca agg.), and F. pallens (F. glauca agg.) were analyzed by polyacrylamide gel electrophoresis (PAGE), in order to evaluate their systematic relationships. Affinities among them were assessed by coefficient of divergence D. Averaged for four enzyme markers, the mean values of coefficient D for comparison of F. pallens with the species of F. valesiaca group were the highest (0.34–0.45) and indicated the remote position of the former species within the studied group. Mean values of D for comparison within F. valesiaca agg. were lower and suggested close mutual affinities. The results are generally in concordance with the recent systematics of the narrow-leaved fescues, on the basis of morphological and anatomical features.
