Résumé
Psychotria carrascoana (Rubiaceae, Psychotrieae) is here described and illustrated. It is endemic to carrasco vegetation, a closed, shrubby, xerophilous vegetation on quartzitic sand soils, on the plateaus of the Serra da Ibiapaba and Serra do Araripe, at altitudes of 800 to 900 m, state of Ceará, Brazil. Because of its reduced, triangular stipules, leaves drying pale green, commonly solitary flowers, and dorsally tricostate pyrenes, this species is placed in Psychotria subg. Heteropsychotria.
