Lowland & montane evergreen guyanan forest & shrubland geocomplex. 1. Evergreen guyanan-orinoquian forest. Ruizterania retusa-Chaetocarpus schomburgkianus communities. Upland plain with seasonally saturated soils. 2. Flooded riparian forest and woodland (“Igapó”): Taralea oppositifolia-Aldina latifolia-Malouetia glandulifera communities. Semipermanently flooded black water stream banks (lotic). 3. Palm swamp: Leopoldinia pulchra-Mauritiella aculeata communities. Permanently flooded black water streams and alluvial ponds (lentic). 4. Riparian shrubland: Simaba orinocensis-Coccoloba ovata communities. Semipermanently flooded by black-water successional vegetation on river and stream banks (lotic). 5. Flooded forest (“Boyal”): Malouetia glandulifera-Molongun laxum-Heteropetalum brasiliense communities. Seasonally flooded alluvial plain. 6. Seasonal evergreen sclerophyllous woodland (“amazonian caatinga”): Eperua leucantha-Micropholis maguirei-Caraipa densifolia communities. Dystrophic podsolized soils on white-sand seasonally ponded paleochannels. 7. Tepuis evergreen montane woodland and scrubs: Kunhardtia rhodantha-Brocchinia hechtioides and Bonnetia crassa-Podocarpus neblinae communities. Moderately deep and semipermanently saturated oligotrophic soils of tepuis plateux. 8. Tepuis evergreen montane forbland & sedge-grasslands: Stegolepis-Xyris-Eriocaulon-Wurdackia communities. Shallow poorly drained oligotrophic stony soils of tepuis inselbergs, plateaus and screes. Graphic geobotanical interpretation based on cited references, our own field data (Autana Tepui) and Google Earth images.
