From 1°11'N-11°10'S and 56°00-77°40'W in the central and western Amazon region in Colombia, Brazil, Peru, and Bolivia at 193(122-400) m elevation in lowland rainforest. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Discussion

  • Some specimens from the Colombian Amazon (e.g., Galeano 1973, García-Barriga 15005, Zarucchi 1712) have wider pinnae than the others, more like those of subsp. hexasticha. One specimen from Amazonas in Peru (Díaz 7131) appears intermediate between subsp. compta and subsp. camptoneura. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A
