Abstract We present the first multi‐gene phylogeny of taxa potentially allied to the fern genus Adiantopsis , one of about 20 genera in the large group of cheilanthoid ferns. Our goals were to clarify natural relationships, examine generic boundaries, and interpret character evolution within a phylogenetic framework. Phylogenetic analysis of combined plastid rbcL and atpA DNA sequences has led to an expansion of generic boundaries in Adiantopsis , a recircumscription that is clearly defensible with morphological data. Biogeographic analyses suggest an origin for the genus in South America, with a minimum of three migrations into the Caribbean. We include a synopsis of the genus and two new combinations.
