Taxonomic studies in the genus Festuca L. (Poaceae) from Argentina y Chile

Abstract

In this contribution we analyze the morphological and anatomical variation in the complex of species related to Festuca chrysophylla using multivariate analysis. We describe the morphology of F. chrysophylla, synonyms are established and the geographical distribution is updated. We establish one new synonymy: F. orthophylla under F. chrysophylla. Furthermore, based on herbarium material, we provide the first record for F. werdermannii for Argentina. We describe in detail the anatomy of both species based on the study of numerous specimens. We select lectotypes for F. chrysophylla and F. deserticola var. juncea.
