Many of the species found on Roraima are unique to the plateau.Plants such as pitcher plants(Heliamphora), Campanula (a bell flower), and the rare Rapateaheather are commonly found on the escarpment and summit. It rains almost every day of the year. Almost the entire surface of the summit is bare sandstone, with only a few bushes (Bonnetia roraim�) and algae present. "[L]ow scanty and bristling vegetation" is also found in the small, sandy marshes that intersperse the rocky summit. Most of the nutrients that are present in the soil are washed away by torrents that cascade over the edge, forming some of the highest waterfalls in the world
