FIGURE. Distribution of Dicorynia. Physical map of the Amazonian region with all analyzed specimens of Dicorynia. A large amount of point overlays leading to reduced number of visible points is due to the large percentage of materials being old collections that rely only on the name of the municipality or similar. Source: NASA with modifications. Note that almost all specimens are contained in areas with less than 200 m high and the high elevations of the Guiana shield may represent a form of isolation between the two species. in A Taxonomic Revision of the Amazonian Genus Dicorynia (Fabaceae: Dialioideae)
