Descripción
Rhizomes short-creeping, 3–5 mm diam.; rhizome scales orangish to ferruginous, narrowly lanceolate, acuminate, inconspicuously comose, margins minutely papillate or entire; fronds 10–50 cm long, clumped; stipes dark red-brown, 1⁄4–1⁄15 the frond length, ca. 1–1.5 mm diam., pilose with acicular, silvery hairs, ctenoid hairs absent; blades narrowly elliptic to lanceolate, 8–40 X 2–6 cm, subtruncate to truncate at bases; rachises abaxially lacking scales, with dense silvery hairs 0.1–0.5 mm; pinnae 10–40 X 2–5 mm, symmetrically dilated at bases, obtuse to acutish at apices, costae decurrent onto rachises; veins free, 1-forked; indument adaxially of dense, silvery, acicular hairs, sometimes septate hairs on costae, veins, and laminar surfaces between veins, abaxially with similar and even denser hairs, appressed clavate hairs absent on the lamina between veins, margins with dense acicular hairs mostly 0.1–0.2 mm; sori round, medial; sporangia with 1–5 hairs on capsules; spores reniform, 64 per sporangium; 2n=74 (CR).A

Discusión taxonómica
This differs from congeners in Mexico by its ferrugineous rhizome scales, proximally truncate to subtruncate blades, absence of scales on the rachises abaxially, relatively small fronds less than 50 cm long, and evenly pilose blades (short silvery hairs on axes as well as between the veins on both sides of the blades). Its affinities may be with species treated in Polypodium rather than to other species of Pecluma.A
