The Cyclanthaceae species stood out in this study for their abundance and frequency. The family was ranked third with regard to FIV and was also reported in lowland forests in the Neotropics Kreft et al. The species with the highest density and widest distribution in the area was Asplundia vaupesiana Harling 87 ind. The most diverse genera were Philodendron, Clusia, Miconia and Heteropsis, which together accounted for The most abundant genera were Philodendron, Guzmania, Asplundia, Anthurium and Alloschemone, which contained Philodendron had the highest generic diversity and abundance in the present study, a result that is consistent with those obtained by Nieder et al.

The species that most stood out with regard to IVe, which together make up These figures show that the two species are well distributed in the area, possibly due to their efficiency in reproduction and dispersion as well as survival strategies specific to each. This indicates a high colonization capacity in the various environments, strata and species of phorophytes available in the forest.
