Introducing a new species of the fern genus Doryopteris (Pteridaceae, Polypodiopsida) from the Neotropics.

Doryopteris adornata is described as a new species from west-central South America (Brazil, Bolivia, Paraguay, and Argentina). The dense indument of scales on the abaxial surface of the lamina is the most prominent diagnostic feature of this new species. Illustrations of the diagnostic characters are provided, as well as a table comparing the morphological characters of D. adornata with those of the two most similar species. The ecology and distribution are described. The conservation status for the new species using World Conservation Union (IUCN) guidelines/criteria is recommended. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 73–77.
