Abstract

Miconia canoi, a new species of Melastomataceae from northern Peru and southern Ecuador is described. Miconia canoi is similar to other scrambling or small shrubs of Miconia found in the páramos and jalcas, but can be easily identified by the combination of glabrous, ovate leaf blades without obvious secondary venation in the adaxial surface, four-merous flowers with persistent bracteoles, glandular pubescent filaments and style, and a capitate to galeate stigma. Based on anther morphology and its mode of dehiscence, M. canoi would be assigned to M. sect. Chaenopleura in the traditional sectional system for this genus. The new species is illustrated and compared to putative relatives.

Resumen

Se describe Miconia canoi, una nueva especie de Melastomataceae del norte del Perú y sur del Ecuador. Miconia canoi es similar a otras especies postradas o rastreras de Miconia de las jalcas y páramos, pero es facilmente identificable por la combinación de hojas ovadas y glabras sin una venación secundaria obvia en la superficie abaxial, flores tetrameras con bracteolas persistentes, filamentos y estilos glandular pubescentes y el estigma capitado a galeado. Basados en la morfología de la antera y su modo de dehiscencia, M. canoi sería asignada a M. sec. Chaenopleura en la división seccional tradicional del género. Se ilustra la nueva especie y se compara con especies putativamente relacionadas.
