This paper resurrects Adiantum weatherbyanum, an overlooked species that occurs in northern Chile, and describes and illustrates a new species, A. rodriguezii, from central Chile. Both taxa belong to the Adiantum poiretii group and were overlooked by the previous authors who worked on the Flora of Chile. Adiantum weatherbyanum is easily recognized by the combination of having of simple and branched, whitish, eglandular hairs on the laminar tissue and veins of the pinnules abaxially, and short ciliate rhizome scales. Adiantum rodriguezii is distinct by its pubescent pinnules on both surfaces; the hairs are simple, articulate, 0.5–1.2 mm long, light brown, with eglandular apices, and restricted to the pinnule veins. Relevant taxa are provided with descriptions, comments, and illustrations of the diagnostic characters. [ABSTRACT FROM AUTHOR]
