New species of Dyckia (Bromeliaceae) from Rio de Janeiro state, Brazil

A new seaside endemic species, Dyckia martinellii B. R. Silva & Forzza, from Rio de Janeiro State, Brazil, is described and illustrated. The genus was represented in this state only by D. pseudococcinea L. B. Smith, from which D. martinellii can be distinguished by a rosette with a larger diameter; longer and wider leaves bearing straight, patent-antrorse larger spines; basal scape bracts densely arranged, with the others longer than or equaling the internodes; floral bracts castaneous, entire, white-lepidote; and sepals orange with a castaneous apex.
