    Type: Vittaria lineata (Linnaeus) J. E. Smith [=Pteris lineata Linnaeus]. Vittaria is a pantropical genus of about 50 species, with only ca. 12 in America. It grows in wet forests of low to high elevation. Our species are mostly very widespread. The genus is distinct in its narrow, undivided fronds, linear, submarginal sori and a single row of areoles between costa and margin. References: Benedict, R. C. 1914.
