From: Trees of Panama: A complete checklist with every geographic range
Distribution maps of four species extending over most of the neotropics. Blue points come from the BIEN database and green from Tropicos (see details in Methods). Many green points are obscured by blue points, but the intent is only to show those places where the Tropicos data extend a range substantially; in these four cases, there is no such extension. N = the total number of unique coordinates, Tropicos and BIEN; R = range extent (103 km2) from all those points
