Abstract
La Amistad International Park (PILA) is a binational protected area from Costa Rica and Panama, which comprises 401,000 ha of natural vegetation. This nature reserve contains 3,046 vascular plant species, including 114 species of Araceae. Anthurium represents the second largest genus in the area, which consists of 62 species (six endemic to PILA). In this paper, a new endemic species of Anthurium is decribed from PILA, A. jorgemendietanum. The affinities are discussed; also photographs and illustrations of this new species are provided.
