Abstract

The taxonomic status of the Mexican cycad Ceratozamia brevifrons is reassessed based on information from habitat, herbaria and living collections in the Botanic Garden 'Jardín Botánico Francisco Javier Clavijero.' Comparison of gross morphology of C. brevifrons with that of C. mexicana as well as analysis of leaflet anatomy, including that of C. robusta, has provided sufficient evidence for the removal of C. brevifrons from synonymy with C. mexicana. A neotype is designated for C. brevifrons and a description is presented. El estatus taxonómico de la cícada mexicana Ceratozamia brevifrons fue revisado con base en información sobre hábitat, especímenes de herbario y las colecciones vivas en el jardín botánico. Al comparar la morfología gruesa de C. brevifrons con la de C. mexicana así como análisis anatómico de los folíolos, incluyendo C. robusta dio suficiente evidencia para remover a C. brevifrons de sinonimia con C. mexicana. Se designó un neotipo para C. brevifrons y se presenta una descripción.
