Range: —Endemic to Bolivia (CO, LP). Ecology: —Fairly common; epiphytic and less commonly terrestrial in humid forests; (500) 1200–2000 m . Notes: —This shares the glabrous sporangia, free veins, glabrous to sparsely short-hairy lower blade surfaces, and the mixture of sparse, acicular hairs ca. 0.5 mm long and shorter, ctenitoid hairs on the rachises with P. divaricata and P. eurybasis var. glabrescens , but the blades are fully pinnate throughout, or nearly so. These two closely allied species may be fully pinnate at the blade bases, but not throughout most of the lamina, the basiscopic pinna margins are decurrent on the rachises, and the bases of adjacent pinnae are approximate or confluent. The remote, broad, apically often rounded pinnae of P. perpinnata provide it with a distinctive habit reminiscent of species of Nephrolepis .
