Abstract

Duranta neblinensis, from Sierra de la Neblina, Amazonas state, Venezuela is described, illustrated, and its morphological relationships with allied species are discussed. This new species is similar to D. obtusifolia, but it differs by its stout spines; pubescent petioles and leaves; apiculate calyx lobes; and fruits with an open, slender, curved rostrum . An updated key to the six Venezuelan species of Duranta is presented, and phytogeographic information about Sierra de la Neblina is provided.

Key words

Resumen

Se describe e ilustra Duranta neblinensis de la Sierra de la Neblina, estado Amazonas, Venezuela, y se discuten sus relaciones morfológicas con las especies afines. Esta nueva especie presenta similitudes con D. obtusifolia, sin embargo, se diferencia por sus espinas gruesas, pecíolos y hojas pubescentes, cáliz con los lobúlos apículados, y los frutos con el rostro abierto y curvo. Se incluye una clave actualizada de las seis especies venezolanas del género Duranta e información fitogeográfica acerca de la Sierra de la Neblina.
