Abstract
in English, Spanish

We describe Solanum baretiaesp. nov., a new species of Solanum section Anarrhichomenum, named in honor of Jeanne Baret, who sailed as the assistant to botanist Philibert Commerson on Louis Antoine de Bougainville's global circumnavigation (1766-1769). The species is similar to Solanum chimborazense, but differs in having larger flowers, more flowers per inflorescence, and different patterns of pubescence on the filaments (pubescent adaxially and glabrous abaxially) and style (papillose to sparsely pubescent). A description, illustration, photos, and comparisons to similar species are included. Also included is a preliminary conservation assessment, along with a brief account of the important role played by Baret during the expedition. The new species appears to be restricted to the Amotape-Huancabamba zone, an area of southern Ecuador and northern Peru known for its exceptional biodiversity.

Se describe Solanum baretiae sp. nov., una nueva especie de Solanum sección Anarrhichomenum, en homenaje a Jeanne Baret, quien viajó como asistente del botánico Philibert Commerson en la circunnavegación mundial de Louis Antoine de Bougainville (1766–1769). La especie se asemeja a Solanum chimborazense pero se diferencia de ella por sus flores más grandes, más flores por inflorescencia, y por tener patrones diferentes de pubescencia en los filamentos (pubescentes adaxialmente y glabros abaxialmemte) y el estilo (papiloso a escasamente pubescente). Se presentan una descripción, ilustración, fotos, y comparaciones con especies similares. Se incluye también una estimación preliminar de su conservación, junto con una descripción breve del papel importante que tuvo Baret durante la expedición. La especie nueva parece estar restringida a la zona Amotape-Huancabamba, un área del sur de Ecuador y norte de Perú notable por su excepcional biodiversidad.
