Abstract


Araracuara Fern. Alonso, a new genus of Rhamnaceae only known from the sandstone plateaus of the Colombian Amazon, is described and illustrated. Its possible affinities are discussed and it is proposed that this is a relictual genus related to the pantropical Colubrina and to a lesser degree with the Amazonian Ampelozizyphus. Also included are both a key to the Colombian genera of Rhamnaceae and a list of representative specimens of the genera studied (some of which have been poorly documented in Colombia).
