Leaves regularly pinnate with 1-veined pinnae, not plicate; rachis 44.5(11.0–87.0) cm long; pinnae 18(6–29) per side of rachis; basal pinna 0.3(0.1–0.5) cm wide, forming an angle of 58(38–77)° with the rachis. Inflorescences rachillae 19(4–40).
Distribution and habitat:— From 1°11’N– 11°10’S and 56°00’– 77°40’W in the central and western Amazon region in Colombia, Brazil, Peru, and Bolivia at 193(122–400) m elevation in lowland rainforest (Fig. 26).
Some specimens from the Colombian Amazon (e.g., Galeano 1973, García-Barriga 15005, Zarucchi 1712) have wider pinnae than the others, more like those of subsp. hexasticha. One specimen from Amazonas in Peru (Díaz 7131) appears intermediate between subsp. compta and subsp. camptoneura.
