INFRUCTESCENCE with pistillate spadix 5 - 6 cm long, 3.5 cm diam.; berries white, 1.1 cm long, 4 - 4.6 mm diam.; seeds 1.4 mm long, 0.5 mm diam., cream-colored.

Habitat

Premontane rain forest and Tropical Lower Montane wet forest life zones.

Distribution

Ranges from Costa Rica to Panama. In Panama, this species ranges no further east than Veraguas (Cerro Tute), except for a disjunct occurrence on Cerro Jefe in Panama Province. All Costa Rican collections are from the northern slopes of the Cordillera Central in Alajue-la, Heredia, and San Jose, and the northern end of the Cordillera de Talamanca in the Tapanti region of Cartago Province. It is to be expected throughout much of the Cordillera de Talamanca.
