Nuevas Combinaciones en Adiantopsis (Pteridaceae, Cheilantheae) de América del Sur

Abstract

The species of the Cheilanthes dichotoma Sw. group (Pteridaceae, Cheilantheae) form a natural group that is morphologically close to the genus Adiantopsis Fe. Molecular analyses using the chloroplast rbcL gene further support the inclusion of these species in the Adiantopsis clade. Two names, C. orbignyana Kuhn and C. recurvata Baker, are transferred to Adiantopsis as A. orbignyana (Kuhn) Ponce & Scataglini and A. recurvata (Baker) Ponce & Scataglini. The other two names, A. dichotoma (Sw.) T. Moore and A. tweediana (Hook.) Prez-Link & Hickey, are also supported and recognized within this genus.
