More than 1200 vascular plant species, distributed over 369 genera and 112 families were encountered in ten plots of 0.1 ha in the humid evergreen rain forests of the middle Caquetá area in eastern Colombia. The total number of vascular plant species in the two most diverse plots ranged from 310 to 313 species 0.1 ha-1. These values indicate that high levels of vascular plant species densities may be encountered all over NW Amazonia, including the Colombian Amazon. The floodplain plots contained fewer vascular plant species and families than the well-drained upland plots. The high species density in the well-drained upland plots was mostly due to comparatively large numbers of species found among the very slender trees of diameter at breast (DBH)≤2.5 cm. Small and slender treelets (DBH < 10 cm) are by far the most species rich habit group. About 50% of the total number of vascular plant species in the plots was exclusively collected with a diameter of less than 2.5 cm. Shrubs, (hemi)epiphytes, and climbers were present with relatively few species. Many of the most species-rich families were tree families. The highest species richness was principally found among tree genera, as well. In this respect the floristic sample from the ten species count plots combined shows much affinity to the local florula around Manaus.
