摘要：

A new species, Utricularia densiflora, from the Brazilian savanna (Cerrado) is described and illustrated. This species was found growing at the Chapada dos Veadeiros National Park, and is distinguished from the other species in the genus by the presence of several rudimentary (or dormant) floral buds, sessile glands in the peduncle, and highly congested inflorescence. Utricularia densiflora is here considered a member of section Oligocista and is morphologically similar to U. erectiflora and U. meyeri. A key of the Utricularia species inhabiting the Chapada dos Veadeiros National Park is provided.
