Discussion

  • There are two separate populations, in Nicaragua and Costa Rica, and eastern Panama. These do not differ from each other except for two variables (apical pinna width, rachilla width?both wider in the Panama population)(t-test, P <0.05).
    Two specimens (Herrera 752, 973) from the same locality in eastern Panama, and from the same locality as other specimens of subsp. procumbens, differ in their undivided leaves. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A

Description

  • Leaves pinnate; petioles drying green or yellowish; veins not raised or slightly raised and triangular in crosssection adaxially; rachis 71.3(42.0-108.0) cm long; pinnae 12(1-28) per side of rachis. Inflorescences staminate flowers deciduous after anthesis; non-fertilized pistillate flowers deciduous after anthesis. (Henderson, A.J. (2011) A revision of Geonoma. Phytotaxa 17: 1-271.)A
