Identification. This species is recognized by its nomadic vine life form (appressed-climbing habit), chartaceous blades with numerous primary lateral veins, inequilat- eral at base, paired inflorescences with slender spadices and orange berries. Grayum (2003) mentioned that this species is very similar to P. rayanum Croat & Grayum (also present on Cerro Pirre), but the latter differs in hav- ing narrower blades and thicker spadices with a longer female portion.

Distribution and ecology. Belize, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, and Venezuela. Philodendron inaequilaterum ocurrs in the semideciduous and evergreen forests of Cerro Pirre, between 90 and 800 m. This species is probably the most abundant of the semideciduous lowland forests of Cerro Pirre. Its spatial distribution appears to be irregular, usually growing in large colonies, both in wooded areas and on open trails and along the banks of rivers and streams.
