Identification. Characterized by short-creeping stems, linear to narrowly lanceolate leaves, deeply pinnatifid blades, and long hairs (up to 6 mm) adpressed to the rachises and petioles. Sori marginal, in tubular indusia at the apex of primary segments, receptacles usually exerted beyond indusia. This species is so locally common and distinct that it has received its own vernacular name: “rooster-tail fern”.

Distribution and habitat. Widely distributed in South America, but apparently absent in Amazon lowlands. Terrestrial in forests.
