Flora of the cangas of Serra dos Carajás, Pará, Brazil: Plantaginaceae

Abstract This is a taxonomic study of the species of Plantaginaceae from the cangas of Serra dos Carajás, Pará, Brazil. We recorded five species, all members of the tribe Gratioleae: Bacopa monnierioides, B. myriophylloides, B. reflexa, Scoparia dulcis and Stemodia verticilata. All five species are widespread in Brazil, and B. myriophylloides is here cited for the first time for the State of Pará. We present detailed descriptions, illustrations, photographs and notes on morphology, distribution and phenology of these species.
