Leaf anatomy in Capsicum species (Solanaceae) from different biogeographic South American environments. In this work, the leaf anatomy of 13 Capsicum species growing in different Biogeographic Provinces was studied. A comparative analysis of the leaf epidermis and its internal structure was carried out in order to find differences and/or similarities among the species and the presence/absence of mesophytic and/or xerophytic characters according to their environment conditions. The density of epidermal cells, stomata, trichomes and stomatal index were statistically analyzed. The results showed that all the species have similar characters; however, there are some unique features that characterize the species as hypostomatic leaves, presence and types of trichomes, presence or absence of crystals and its variable disposition, fibers in main vein, and probable presence of tannins. Regarding the presence of xeromorphic or mesomorphic characters, the differences were not significant among the species from different environments except for the amphistomatic leaves and the abundance of crystals, and trichomes in species from dry environments. We conclude that the similarity of the leaf epidermal variables and the internal structure observed in the Capsicum species are responding more to a grouping according to their phylogenetic relationships than to the environmental conditions where they live. Se estudió la anatomía foliar en 13 especies de Capsicum L. que crecen en diferentes Provincias Biogeográficas. Se realizó un análisis comparativo de la epidermis foliar y de la estructura interna de lámina y pecíolo para hallar diferencias y/o similitudes entre las especies y la presencia/ausencia de caracteres mesomórficos/xeromórficos según el ambiente que habiten. La densidad de las células epidérmicas propiamente dichas, de los estomas, de los diferentes tipos de tricomas y el índice estomático fueron estadísticamente analizados. Los resultados indican que todas las especies presentan características similares en sus hojas. Sin embargo, en determinadas especies se observaron algunas particularidades, tales como hojas hipostomáticas, presencia y tipos de tricomas, presencia, disposición y tipo de cristales, fibras rodeando la vena media y probable presencia de taninos. No se encontraron diferencias significativas entre especies que habitan distintos ambientes, excepto aquellas especies procedentes de ambientes secos con hojas anfistomáticas y abundancia de cristales y tricomas. Se concluye que las similitudes de las variables epidérmicas y de la estructura interna de la hoja, observadas en las especies de Capsicum, estarían respondiendo a un agrupamiento según sus relaciones filogenéticas más que a las condiciones ambientales donde habitan.
