Resumen:
The recent rediscovery of Jatropha riojae, which was considered as
probably extinct, led to a taxonomic re-evaluation of the species due to
its problematic circumscription with respect to morphologically similar
species of Jatropha section Loureira subsect. Loureira. Based on our
study, J. riojae is accepted, taxonomic clarifications are made,
including the designation of a lectotype for the name, a complete
description of vegetative and reproductive structures is provided, and
the species is illustrated and compared to others with which it has been
confused. The geographical distribution of J. riojae is clarified as
endemic to the municipality of Acatlan, Puebla, Mexico in the south of
the Balsas River Basin. To determine the conservation status of the
species, the risk assessment method of theMexican Red List (NOM
059-SEMARNAT-2010) was applied, indicating that J. riojae should be
assigned to the ``Endangered'' category. A re-evaluation of the
species under the IUCN criteria indicated that it should be assigned in
the ``Critically Endangered'' (CR) category.
