The fern genus Osmolindsaea has recently been recognized as separate from Lindsaea on the basis of molecular data. Here we provide a taxonomic revision of Osmolindsaea based on morphological examination of herbarium specimens and molecular phylogenetic analysis of five plastid loci (trnL-trnF, trnH-psbA, rpoC1, rps4, and rps4-trnS). We recognize seven species in the genus, two of which are here described as new to science ( O. latisquama and O. leptolepida ) and three are transferred to this genus from Lindsaea ( O. himalaica , O. minor , and O. plumula ). A key to the species is provided, as well as descriptions, illustrations, synonymy, and a list of examined specimens for each species.
