Habitat notesMembers of the genus are low trees in tropical forests. The distinction between Psychotria and the genus Cephaelis are not well known and many species were formerly placed there. Many species produce important chemicals, such Psychotria ipecacuanha or the number of DMT-containing taxa, namely Psychotria viridis. Others are rare or even nearly extinct due to deforestation, mainly species of central Africa and the Pacific.
