    Abstract

    © 2015 Magnolia Press. Philcoxia rhizomatosa, a new species of the carnivorous genus Philcoxia from tribe Gratioleae (Plantaginaceae), is here described and illustrated. The species has larger leaves than the other members of the genus, presents a conspicuous and branched rhizome and is the only one with entirely glabrous inflorescence, pedicel and calyx. This taxon is possibly endemic to a sandy outcrop in the transition vegetation between the Cerrado and the Caatinga in the municipality of Botumirim, Minas Gerais, Brazil. Preliminary tests for carnivory were performed and showed the presence of nematodes and activity of phosphatase on leaf surfaces, suggesting that P. rhizomatosa is a carnivorous plant.
