摘要：
A new section, Miconia sect. Calycopteris, is described and characterized. It includes 15 species previously recognized within Calycogonium, Clidemia, Henriettella, Leandra, Miconia, and Ossaea. Species descriptions, nomenclatural information, specimen citations, and eco-geographical characterization for each of the eight species occurring on Hispaniola are presented, along with an identification key. Section Calycopteris likely represents a monophyletic group within the Caribbean clade of tribe Miconieae (Melastomataceae) and is restricted to Hispaniola and Cuba. The section is characterized by strongly 4-lobed ovaries and hypanthia, calyx teeth that are flattened parallel to the floral radii, and seeds with a distinctive, dark-colored and expanded raphe. The following new combinations and new names are presented: Miconia hispidula, M. calycopteris, M. tetragonoloba, M. formonensis, M. nanophylla, M. reticulato-venosa, M. vegaensis, and M. maculata.
