From 0°04'N-1°18'S and 72°05-72°52'W in the western Amazon region in Colombia (Amazonas, Caquetá) at 270(200-360) m elevation in lowland rainforest. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Discussion

  • One specimen (Galeano 2080) has larger leaves and exceptionally large fruits (13.3 cm long and 11.5 cm diameter), and may be a hybrid with a morphotype of subsp. chelidonura. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Description

  • Leaves regularly pinnate with 3-5-veined pinnae (except for basal and apical ones), not plicate; rachis 34.1(27.5-48.5) cm long; pinnae 16(10-20) per side of rachis; basal pinna 0.3(0.2-0.6) cm wide, forming an angle of 70(50-87)° with the rachis.
