Abstract
As a result of a recent alpha-taxonomic study of the genusMagnolia s. str. in Mexico and Central America, four new species and four new subspecies ofMagnolia sect.Theorhodon are proposed, includingM. iltisiana, M. panamensis, M. tamaulipana, M. sororum subsp.lutea, andM. pacifica, consisting of three subspecies:pacifica, pugana, andtarahumara. Additionally, a new combination,M. guatemalensis subsp.hondurensis, is made, and a new section,M. sect.Splendentes, is erected for the Caribbean species. The results have implications for understandingMagnolia biogeography, andM. tamaulipana has potential for horticulture in temperate zones. Keys to genera, sections, and species, and maps of species distributions are presented.Magnolia grandiflora L. andM. schiedeana Schltdl. are lectotypified.

Como resultado de un estudio alfa-taxonómico reciente del géneroMagnolia s.str. en México y Centro América, se proponen cuatro especies nuevas y cuatro subespecies nuevas deMagnolia sect.Theorhodon, incluyendoM. iltisiana, M. panamensis, M. tamaulipana, M. sororum subsp.lutea y.M. pacifica, la última consiste de tres subespecies:pacifica, pugana ytarahumara. Adicionalmente, se hace la combinaciónM. guatemalensis subsp.hondurensis y se erigeM. sect.Splendentes para las especies del Caribe. Los hallazgos tienen implicaciones en el entendimiento de la biogeografia deMagnolia y.M. tamaulipana tiene potencial en la horticultura de zonas templadas. Se presentan claves para géneros, secciones y especies, y mapas de distribución para las especies.Magnolia grandiflora L. yM. schiedeana Schltdl. son lectotipificadas.
