Psychotria is a plant genus of 1900 species[3] in the family Rubiaceae. Members 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.
Very conspicuous is that several species have dark spots on their leaves. These spots are nodules and hold endosymbiotic bacteria. 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.
