MENDOZA-CIFUENTES, Humberto; POSADA-Η, Mauricio  and  DAVID, Heriberto. A new species of Miconia (Melastomataceae) with connate anthers from Colombia. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2019, vol.43, n.167, pp.250-254. ISSN 0370-3908.  https://doi.org/10.18257/raccefyn.848.

The Miconieae tribe comprises about 1,900 Neotropical species and recent studies propose only one genus for the tribe, Miconia, which includes all of the genera previously considered including Tococa. Here we describe and illustrate a new species of the genus Miconia with lateral connate anthers from the department of Chocó, Colombia. This new taxon is associated with the species of the Miconieae tribe with laterally coherent anthers in a ring stamens such as Tococa symphyandra and Miconia croatii. This new taxon is characterized by the indument on branches with elongate and alveolate trichomes, bullate leaves, closed calyx in buds and with large dorsal teeth, bigger petals and style, and a truncated ovary apex. This new species grows in very humid areas of the sub-Andean forest in the central region of the Western Cordillera and at present, it is known only from the type locality. © 2019. Acad. Colomb.
