Anthurium jaimeanum Croat & C. E. Cerón and A. pahumense C. E. Cerón & Croat (Araceae) are described and illustrated. The two species are members of A. sect. Porphyrochitonium Schott from the W slopes of the Ecuadorian Andes in Pichincha Province. Anthurium jaimeanum occurs at 1800 m in a premontane rain forest life zone, whereas A. pahumense is found at 1800–2200 m in a lower montane wet forest life zone. The new species are unusual in A. sect. Porphyrochitonium, a group characterized by having short internodes and glandular punctate blades, in that they have unusually long internodes.
