Anthurium ochranthum is known from Costa Rica to Panama from sea level to 1,350 m, most commonly in tropical wet forest but also in wetter parts of tropical moist forest and in premontane wet and premontane rain forest. The species is placed in section Belolonchium and is recogni/ed by its terrestrial habit, bright yellow, long-tapered spadix, violet-purple and white berries, and the leaf blades that have the anterior lobe sometimes concave along the margins. It is most closely related to A. pluricostatum. See the discussion following that species for differences.
