Note Steyermark (1972), who has incorporated Cephaelis into Psychotria, anno- tated many specimens of "Cephaelis axillaris Sw." as Psychotria aubletiana Steyermark. In the synonomy under P. aubletiana he (1974) listed: "Cephaelis axillaris Sw., Prodr. Veg. Ind. Occ. 45: 1788, no Psychotria axillaris Willd., Sp. PI. 1: 962. 1798, basada sobre Ronabea erecta Aubl., ni Psychotria axillaris Vell., Ft. Flum. 67: 2. pl. 32. 1827." He recognized 7 varieties, 5 of which occur in Venezuela.
