Identification. Anthurium trilobum is characterized by having slightly long stems, persistent cataphylls such as fibers, blades with naked ribs, trilobed with falcate lat- eral lobes, reflexed and brittle green spathes, and stipitate yellow spadices. Anthurium trilobum is the only species on Cerro Pirre that has trilobed blades with falcate lateral lobes, although in some cases, it can be confused with A. panduriforme (for the differences, see couplet 11 of the key).

Distribution and ecology. Colombia, Costa Rica, Ecuador, and Panama. This species is very common in the semideciduous and evergreen forests of Cerro Pirre and generally ocurrs up to 1000 m, although there are records that this species can ocurrs on the top of the mountain, ca 1400 m ( Carlsen and Croat 2007).
