Habitat
In Tropical dry( T-df), Tropical moist (T-mf), Tropical wet (T-wf), Prernontane wet (P-wf), and Prernontane rainforest (P-rf) life zones (Hold-ridge, 1967).
Phenology
Flowering of D. oerstedii occurs throughout the year, but with the heaviest flowering at the end of the dry season and the first part of the rainy season, April to September. Fruit maturation is more regularly scattered throughout the year.
Distribution
Dieffenbachia oerstedii ranges from Mexico( Veracruz, Oaxaca, Chiapas, and Tabasco) mostly along the Caribbean slope in Central America in Guatemala, Honduras, Nicaragua, and Costa Rica (where it occurs on both slopes) and west-central Panama. The species also occurs on the Pacific slope of El Salvador (Department of Ahuachapan).
Diagnostic
This species is characterized by its small stature (generally less than 1 m tall); frequently clustered stems; and sharply C-shaped petioles that are whitish at the base and sheathed.

Native to:

Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico Central, Mexico Gulf, Mexico Southeast, Mexico Southwest, Nicaragua, Panamá
