 Plants terrestrial. Rhizomes 3.15–5.2 mm thick, with brown, rigid, narrow-triangular scales, apex attenuate, base truncate, margins dentate with short to long-ciliate apex. Fronds erect, 3–5 times forked, petiole 2.5–6 mm thick, ultimate branches 4.5–18.5 × 0.6–3 cm, linear-lanceolate, apex pinnatifid, base truncate, abaxial surface densely scaly on the rachis, scales stramineous, triangular, apex filiform, base truncate, margins long-ciliate, adaxial surface sparse to densely covered by arachnoid scales, segments linear 0.5–2 × 0.15–0.35 cm, margins strongly revolute, abaxial surface with arachnoid scales on midrib, secondary veins and laminar tissue. Buds with light-brown, triangular scales, apex filiform, base truncate, margins long-fimbriate, pseudoestipule present. Veins 1-forked. Sori medial, without paraphyses.   
 Distribution and habitat: — Brazil (Bahia, Distrito Federal, Espírito Santo, Goiás, Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo), Bolivia, Colombia, Costa Rica, Ecuador, Hispaniola, Paraguay, Peru, and Venezuela. In Brazil, this species occurs along roads, trails and forest edges in the Cerrado and Atlantic Forest domains at 500–1850 m.   
 Notes: — Sticherus lanuginosus differs from the other Brazilian species of Sticherus by having erect fronds with strongly ascendant branches, rhizome scales with margins dentate and a few apical cilia, and bud scales long-fimbriate. It forms large populations in the south and southeast of the country and smaller and disjunct populations in the northeast and midwest.   
 In the original description of Gleichenia lanuginosa, Fée cited three different collections, Blanchet 3706, Claussen 88 and St.-Hilaire B’ 273. We found nine specimens of Blanchet’s collection, none of Claussen’s, and one of St.- Hilaire’s. The Blanchet collections were located in P (three), BR (two), B (two), and one each in K and NY. The K specimen has an original label of Blanchet, but without his signature. The NYspecimen doesn’t have the original label of Blanchet, but only a transcript label with a Morics signature. The BR material of Blanchet’s collection both have transcript labels and are from Herbarium Martii. The B specimens have original labels but it lacks Blanchet’s signature. At P, we found one complete specimen with original label with Blanchet’s signature and here we choose it as lectotype since the other two specimens at P both have an original label but lack Blanchet’s signature. Regarding the St.-Hilaire collection, we found one specimen at P under the name Gleichenia ramosissima with a handwritten description, as cited in the original protologue of Mertensia lanuginosa. In this case, G. ramosissima it is not a valid name, since it has not been published.
