Identification. Anthurium friedrichsthalii is characterized by its epiphytic habit, pendant leaves, black-glan- dular punctate (only on the lower surface), linear blades, relatively short petioles and yellow-orange berries. In the study area, A. friedrichsthalii can be confused with A. pendens Croat , but the latter differs by having blades drying blackish, black-glandular punctate on both sur- faces and flowers with all stamens exposed (when dry).

Distribution and ecology. Colombia, Costa Rica, Ecuador, Nicaragua, and Panama. On Cerro Pirre, this species is generally found at areas below 800 m, along the semideciduous and evergreen forests. It is usual to observe the individuals of this species in the highest branches of the host trees (near the forest canopy), approximately at 15– 20 m.
