Description: Upland savannas that develop under different topographic and edaphic conditions. On the flat plains of the Gran Sabana in Venezuela, Brazil and Guyana, on clayish or lateritic soils and subjected to frequent fire dynamics, natural or anthropogenic. The grass layer is 1-1.5 m tall with 20-70% coverage; dominant species are of the genera <i>Trachypogon, Bulbostylis</i>, and <i>Axonopus</i>. In other circumstances they develop on the mostly sandy slopes of the Guiana Shield or of the massifs (tepuys). The composition and proportions of herbaceous versus shrubby elements can vary depending on nutrient and moisture availability conditions at their location. Diagnostic species are <i>Euphronia guianensis, Bonyunia minor, Miconia</i> spp., <i>Trattinnickia burserifolia, Palicourea rigida, Bonnetia sessilis, Calea divaricata, Ochthocosmus</i> sp., <i>Ouratea roraimae, Cyrilla racemiflora (= Cyrilla antillana), Tetrapterys</i> sp., <i>Licania incana, Tococa nitens, Brocchinia reducta, Stegolepis</i>, and <i>Scleria</i> sp., many of them endemic.
