Identification. According to Croat and Ortiz (2016), Anthurium cuspidatum Mast. is characterized by its usually terrestrial habit, short internodes, persistent cataphylls as fibers, broadly ovate blades wich drying greenish, six to nine pairs basal veins (one to three free from each other) and purple to dark-purple spadices.

Distribution and ecology. Colombia, Costa Rica, Ecuador, and Panama. On Cerro Pirre this species generally grows in cloud forests, which are located above 1000 m. This species frequently presents terrestrial habit, but in places with abundant humidity and mosses, it can grow as an epiphyte.
