In this contribution the rediscovery of the bromeliad Dyckia excelsa in Mato Grosso do Sul state, central-western Brazil, is reported. This species was first described based on a single individual from a particular collection in 1993 with no precise locality. Illustrations and a brief discussion on the leaf anatomy of the species are provided. One additional species, Dyckia gracilis, which has been overlooked by previous authors, is included in the list of Bromeliaceae of Mato Grosso do Sul State. An updated key for Dyckia species from the region of D. excelsa is presented. The status of D. excelsa in Mato Grosso do Sul State, Brazil, is discussed, and recommendations for its conservation are offered.
