CATE Araceae, 17 Dec 2011.

Premontane wet forest, Tropical wet forest and Premontane rain forest life zones.
Flowering in Philodendron hebetatum apparently occurs throughout the dry season and first part of the rainy season in Panama, from December through July. Post-anthesis inflorescences have been collected from January through October (except September). Immature fruits have been collected in June and July. South American follow more or less the same pattern as those from Panama.
Ranges from Panama to Colombia (Chocó) and Ecuador (Carchi, Esmeraldas, and Pichincha) along the Pacific coast. It is to be expected in adjacent Costa Rica.
