Abstract

Two new species of Ctenitis (Dryopteridaceae) from South America are described and illustrated: Ctenitis christensenii is endemic to southeastern Brazil and C. glandulosa occurs from southeastern to northeastern Brazil and in Guyana. An identification key and notes about the distribution, habitat and taxonomy of the new species, C. falciculata and allies are provided. Moreover, seven lectotypifications and two new synonyms are proposed.
