Lentibulariaceae do Parque Nacional do Itatiaia, Brazil

Abstract

Lentibulariaceae is cosmopolitan, composed of three genera, Genlisea, Pinguicula, and Utricularia, containing ca. of 29, 100, and 220 species, respectively. The Itatiaia National Park is an elevated area with many rising rivers, lakes, wet places, and bromeliads. Therefore, it is promising to the occurrence of Lentibulariaceae species. However, studies in Lentibulariaceae in the area are scarce, restricted to a few old species lists. We present here the floristic treatment of the family in the Itatiaia National Park. Eight species were recorded, all belonging to Utricularia. All species occur in wet places of the Itatiaia Plateau, and only U. reniformis also occurs in the rivers of non-elevated areas. An identification key to the species, detailed descriptions, comments, and photos are provided.
