Leaves 15(6-25) per stem; sheaths 45.4(14.0-110.0) cm long; petioles 56.8(20.0-122.0) cm long; rachises 135.4(68.0-231.0) cm long, 13.3(7.9-20.1) mm diameter; pinnae 10(6-17) per side of rachis; basal pinna 57.9(34.0-92.0) cm long, 2.4(0.7-7.5) cm wide, forming an angle of 53(30-74) with the rachis; apical pinna 45.0(36.0-58.0) cm long, 15.3(4.5-22.5) cm wide, forming an angle of 13(7-20) with the rachis. Inflorescences branched 1 order (rarely 2 orders), with a well-developed peduncle, short rachis, and several rachillae, these erect at anthesis; prophylls and peduncular bracts fibrous, covering all or part of the rachillae at anthesis; prophylls 46.0(30.0-59.0) cm long; peduncular bracts 56.7(50.0-65.0) cm long, inserted 6.2(2.5-11.0) cm above the prophyll; peduncles 16.3(8.5-25.5) cm long, 10.4(4.7-19.0) mm diameter; rachillae 9(2-16), 35.5(15.5-75.0) cm long, 6.3(4.5-9.7) mm diameter; proximal lips of flower pits irregularly shaped, often acute or acuminate, completely covering pits before anthesis; fruits scarcely compressed, obovoid, with obscure longitudinal ridges, 12.2(8.8-16.3) mm long, 7.9(5.8-11.5) mm diameter.

一般資料:
Specimens occur in several different populations. The northernmost specimens, from two localities in eastern Panama, are distinct in their short rachillae and acuminate proximal lips. The southernmost specimens, in southwestern Ecuador, differ slightly from those in southwestern Colombia and northwestern Ecuador. Although there are too few specimens to test for differences, they have shorter and narrower apical pinnae.
