Identification. This species is distinguished by its widely ovate to ovate-triangular, coriaceous blades, creamywhite spadices, and greenish-white reflexed spathes. Additionally, Anthurium curvispadix has very long cataphylls (up to 18 cm long). The closest species to A. cur- vispadix on Cerro Pirre is A. cucullispathum Croat , but the latter species has smaller cataphylls, blades usually more than twice as long as wide and erect-cucculate spathes.

Distribution and ecology. This species is currently endemic to Panama. On Cerro Pirre it grows generally in the mid-elevation evergreen forests (between 500 and 800 m). Sporadic individuals of this species can be observed in tree branches at 10– 20 m.
