In the present paper we describe two new endemic species of Anthurium, discovered during field trips to study Araceae flora Chucantí Nature Reserve (Reserva Natural Chucantí) located in province Darién, Panama. Anthurium annularum sp. nov., a member section Xialophyllium, is principally characterized by its hemiepiphytic climbing habit, stems with ring-shaped nodes short internodes alternating much longer internodes, yellow-green spadix and pale green globose berries which are nearly translucent toward base. A. chucantiense Polyneurium, epiphytic at stem apex, terete petioles, blades obscure primary lateral veins, greenish orange narrowly ovoid, bluntly pointed red-orange berries.
