Reference: NatureServe Biotics 2019
Description: Scrub to herbaceous meadows that have in common a substrate composed of peat that forms under hyper-humid, cool conditions at the top of the highest tepuis of the Guiana Shield, at altitudes between 1500-2600 m asl in Venezuela and Brazil. The physiognomies vary from dense short shrublands to shrublands up to 3 m high with an herbaceous stratum dominated by rosette plants. It also can form open herbaceous meadows. The summits of the different tepuis have characteristics endemic species, which also makes the composition vary from one to another. Diagnostic species are <i>Bonnetia maguireorum, Archytaea multiflora, Tepuianthus auyantepuiensis, Blepharandra hypoleuca, Chimantaea</i> spp., <i>Bonnetia multinervia, Malophyton chimantense, Adenanthe bicarpellata</i>, and <i>Ledothamnus</i> spp. Under conditions of high water saturation, a marsh or bog develops with characteristic species such as <i>Drosera roraimae, Saxofridericia spongiosa, Lagenocarpus rigidus, Xyris involucrata</i>, and <i>Utricularia</i> spp. The macrogroup also includes a <i>Stegolepis</i>-dominated meadow up to 1.5 m high on slopes which present a peat layer in the substrate. It occurs on some locations in the Gran Sabana at 900-1400 m elevation. Characteristic species are <i>Drosera roraimae, Saxofridericia spongiosa, Lagenocarpus rigidus</i>, and <i>Xyris involucrata</i>.
