New species of Anthurium (Araceae) from Chucantí Nature Reserve, eastern Panama

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