Description:
This macrogroup represents three types of flooded forests of the Orinoquian Llanos in Colombia and Venezuela. The first are those inundated or saturated almost permanently from seasonal flow or seepage of blackwater or clearwater and mostly occurring in the lower terrain towards the eastern part of the Llanos in Colombia and Venezuela, with characteristic species such as <i>Protium calanense, Pseudolmedia laevigata, Manilkara bidentata, Socratea durissima, Scheleea, Jessenia, Geonoma, Bactris, Nectandra, Alchornea, Inga, Jacaranda, Amanoa guianensis, Bactris</i> sp., <i>Euterpe oleracea, Geonoma maxima, Calophyllum lucidum, Coccoloba</i> sp., <i>Mabea nitida, Protium heptaphyllum, Symphonia globulifera, Sapium salicifolium, Virola surinamensis</i>. The second type included is the "varzea" forests along the floodplains of the Orinoco River, flooded for up to six months/year and alternating with marshes and flooded savannas. Characteristic species of the Orinoco varzea forests are <i>Combretum frangulifolium, Gustavia augusta, Etaballia dubia, Albizia corymbosa, Spondias mombin, Mabea nitida, Homalium racemosum, Symmeria paniculata, Copaifera pubiflora, Campsiandra laurifolia, Eschweilera tenuifolia, Astrocaryum aculeatum, Acosmium nitens, Caraipa llanorum, Sorghastrum setosum (= Sorghastrum parviflorum), Hymenachne amplexicaulis, Eleocharis filiculmis</i>. The third type represents the seasonal deciduous gallery forests inundated for a shorter period of time that occur along the floodplains of the Llanos de Apure in Venezuela, and those that flow into the Meta River in Colombia. In this type, common deciduous species include <i>Cordia collococa, Sapindus saponaria, Astronium graveolens, Hura crepitans, Coccoloba caracasana, Pradosia caracasana, Guazuma ulmifolia, Macrolobium</i> sp., <i>Tabebuia rosea, Stemmadenia</i> sp., <i>Calophyllum lucidum, Xylopia emarginata, Protium crassipetalum, Socratea elegans, Vochysia ferruginea, Lacistema aggregatum</i>.
