Distribution and habitat: — Paraguay and Uruguay. In Brazil, this species occurs in the states of Espírito Santo, Rio de Janeiro, São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul ( Fig. 10A View FIGURE 10 ), mainly in the “restingas” of Atlantic Forest and occasionally in other forest types above 400 m elevation.

Notes: —This species is unique because it has cartilaginous pinnae margins as well as longer scales with base rounded and long-acuminate to the filiform apex on all lamina parts, making it easy to identify. In Brazil, usually occurs in coastal areas, but it is found inland in the states of Rio Grande do Sul, Santa Catarina, and Paraná, as observed by de la Sota (1966). Specimens from Minas Gerais and Bahia determined as P. lepidopteris were reidentified as P. hirsutissima or P. minarum . The specimen Handro 350 (SP) is P. lepidopteris from Minas Gerais; however, it is from a cultivated plant from the São Paulo Botanical Garden and there is no reliable information about the origin of the plant. Therefore, we chose not to record (or mention) the species for Minas Gerais, until new records confirm its occurrence in the state.
