Identification. Anthurium ramonense is characterized by having a rosette-epiphytic habit, conglomerate roots, short petioles, black glandular-punctate blades only on the lower surface and long inflorescences. In the study area this species can be confused with A. salvinii Hemsl. , which differs in having ribbed petioles and cucculate cataphylls.

Distribution and ecology. Colombia, Costa Rica, Nicaragua, and Panama. This species of wide distribution is common to observe it in the evergreen and semideciduous forests of Cerro Pirre. Generally, it has an epiphytic habit, but when it falls from the branches of the host trees, can develop an accidental terrestrial habit.
