Distribution of Festuca glyceriantha (•), F holubii (A), F. densipaniculata (?), andF. monguensis (#). abaxial sclerenchyma and all vascular bundlesfree (versus continuous abaxial sclerenchyma withsome girders persent). The characteristics of mixedinnovations with brown, striate, fibrous sheaths inF. dinirica suggest a close relationship with F In South America, this section is not verycommon and is still poorly studied. The Colombianand Ecuadorian species, F andicola, is geographi-cally the nearest species within F sect. Aulaxyper. Distribution and habitat.—Festuca dinirica isendemic to Venezuela (Lara) and occurs at an alti-tude of about 3200 m where it forms small tussocksin shrubby-grassy paramos and is associated withvarious species of Blechnum, Espeletia, Hypericum,Calamagrostis, Chusquea, and Rhynchospora.
