Novelties in the genus Stylosanthes (Leguminosae, Papilionoideae, Dalbergieae) for Mexico

Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, Apdo. Postal 70–233, 04510 Mexico City, Mexico
México Stylosanthes leticiana S. rosalindae S. gretheriae taxonomía Valle de Tehuacán-Cuicatlán Eudicots

Abstract

Taxonomic and molecular studies support the description of three new species of the genus Stylosanthes (Leguminosae, Papilionoideae, Dalbergieae), occurring in Mexico. These new species are described and illustrated. In addition, habitat data, distribution maps and comparative SEM photographs of the fruits are given for the new taxa and their related species. Stylosanthes leticiana has a wide distribution in Mexico and affinity with S. humilis. Stylosanthes rosalindae is distributed in central-southern Mexico, mainly in the Tehuacán-Cuicatlán Valley, and is morphologically similar to S. subsericea and S. viscosa. Stylosanthes gretheriae grows in western Mexico and has similarities to S. guianensis.
