Premontane wet forest, Tropical dry forest, Premontane moist forest, and Tropical moist forest.


Philodendron pogonocaule ranges from Colombia (Narino) to Ecuador (Canar, Cotopaxi, El Oro, Esmeraldas, Los Rios, Manabi, Pichincha), at elevations of 60-1,950 m, in Premontane dry forest, Premontane moist forest, Premontane wet forest and Tropical moist forest. In La Planada, the species is occasionally seen along the ridge at the end of the trail above La Posada and along the Sendero Natural.

Philodendron pogonocaule Madison ranges from southern Colombia (Narino) to northern and central Ecuador (Pinchincha, Emeraldas, Los Rios, Cotopaxi, and Manabíi).
