Ecuador present
From 2°40-3°38'S and 78°00-78°30'W in Ecuador on eastern Andean slopes at 1778(1470-1920) m elevation in montane rainforest. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Discussion

  • Subspecific variation: - There is geographic discontinuity, and specimens come from three different mountain areas. Specimens from the Cordilleras Cutucú and Cóndor have more pinnae per side of the rachis than those from the eastern slopes of the main Cordillera. However, there are too few specimens to test for differences. Jean-Christophe Pintaud (pers. comm.) reports that this subspecies also occurs in adjacent Peru. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Description

  • Leaves veins raised and rectangular in cross-section adaxially; basal pinna 1.3(0.6-2.0) cm wide; apical pinna 7.3(2.7-11.3) cm wide.
    Inflorescences prophyll margins with irregular, spine-like projections; flower pits usually spirally arranged, distantly spaced (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A
