Abstract
A taxonomic study of Leandra in the Ecological Reserve of Macaé de Cima is presented. The genus is represented by 35 species. Three new synonyms are recognized and three lectotypes are designated. A key to the identification of the taxa are also provided, as well as descriptions, illustrations, geographic distribution data and comments about taxonomic and morphological particularities. Leandra aspera, L. atroviridis, L. eriocalyx, L. laxa, L. mollis, L. multisetosa, L. sphaerocarpa, and L. tetragona are endemic to Macaé de Cima. These species and L. altomacaensis, L. breviflora, L. hirta var. hirta, and L. magdalenensis are endemic to the State of Rio de Janeiro. Leandra altomacaensis, L. glazioviana, L. riedeliana, and L. truncata represent new occurrences to the studied area. Leandra aspera, L. atroviridis, L. multisetosa, L. sphaerocarpa, and L. tetragona are ilustrated for the first time.
