From 8°34'-9°25'N and 78°48'-80°56'W in Panama at 483(60-768) m elevation in lowland rainforest. There are two separate populations occurring 170 km apart in Panama. The western population, on the eastern end of the Central Cordillera, has shorter stems, shorter petioles, and shorter and thinner basal pinnae than the eastern population, on the western end of the Serranía de San Blas. The western population also occurs at a higher mean elevation- 722(695-768) m versus 303(60-450) m.
