A revision of the Miconia ulmarioides complex (Melastomataceae: Miconieae)

  • Nichole M. TiernanEmail author
  • Fabián A. Michelangeli


A taxonomic revision is presented for ten species that comprise the Miconia ulmarioides complex (Melastomataceae: Miconieae). This group is characterized by four-merous flowers with four-locular ovaries, short, stout, pink to fuchsia anthers, punctiform or truncated styles and short outer calyx teeth. All species in the group are small trees and shrubs from the northern Andes in Colombia and Venezuela and the Sierra Nevada de Santa Marta and Coastal Cordillera of Venezuela, with one species (M. nubicola) endemic to Jamaica. Leandra ossaeoides is transferred to Miconia (as M. ossaeoides) and M. albertii is synonymized under M. ulmarioides. We designate new lectotypes for M. arbutifolia, M. spinulosa, M. inaperta, M. octoscenidium, M. spinulosa var. subintegrifolia, M. ulmarioides, M. aegrotans, and M. ulmarioides var. fendleri. Descriptions, morphological discussions, key to taxa, and photographs of key features are included for all species.

Se present a una revisión taxonómica del complejo de Miconia ulmarioides (Melastomataceae: Miconieae). Este grupo se caracteriza por presentar flores tretrameras con ovarios 4-loculares, cáliz con dientes externos cortos, estambres cortos, robustos, rosados a fucsia, y estilos puntiformes o truncados. Todas las especies son árboles pequeños o arbustos del norte de los Andes en Colombia y Venezuela, la Sierra Nevada de Santa Marta y la Cordillera de la Costa en Venezuela, con una especie (M. nubicola) endémica a Jamaica. Leandra ossaeoides es transferida a Miconia (como M. ossaeoides) y M. albertii es sinonimizada bajo M. ulmarioides. Se designan lectotipos para M. arbutifolia, M. spinulosa, M. inaperta, M. octoscenidium, M. spinulosa var. subintegrifolia, M. ulmarioides, M. aegrotans, and M. ulmarioides var. fendleri. Se incluyen para todas las especies descripciones, discusiones morfológicas, una clave para su identificación, así como fotografías para la mayoría de ellas.
