16d. Geonoma deversa subsp. quadriflora Henderson, subsp. nov. (Appendix IV, Plates 27–30) A Geonoma deversa subsp. deversa foveis floralibus quarternatis differt. Type: COLOMBIA. Amazonas: road from Leticia to Tarapacá, ca. 7 km N of Leticia, 180 m, 17 March 1990, G. Galeano, R. Bernal, A. Henderson & S. Churchill 2112 (holotype COL!, isotype NY!). Leaf rachis 71.7(38.5–92.5) cm long. Inflorescences peduncles 6.4(5.2–8.0) mm in diameter; rachillae 2.6(1.7–3.4) mm in diameter. Distribution and habitat:— From 3°20’– 7°37’S and 68°46’– 73°28’W in the western Amazon region of Colombia, Brazil, and Peru at 137(95–180) m elevation in lowland rainforest (Fig. 16). The outlying specimens from Brazil probably appear isolated only because the intervening area is poorly collected. See discussion under G. deversa subsp. deversa for possible hybrids.
