| description | Background and Aims: The revision of herbarium specimens of Hoffmannia (Rubiaceae) and the extensive exploration by the authors has resulted in the discovery of new species within this genus. Hoffmannia uxpanapense Cast.-Campos and Bautista-Bello is described and illustrated as a new species of the Rubiaceae family from southern Mexico, collected in the evergreen tropical forest of Uxpanapa in Veracruz and Oaxaca.Methods: The specimens of the genus Hoffmannia of the state of Veracruz were studied, a matrix of morphological data was elaborated, and a cluster analysis was carried out to differentiate the species and to detect their similarities.Key results: The specimens identified as “H. wendtii” presented different morphological characters to the species already described in this genus. As this name has not been published, it was considered as a new species that still needs to be formally described. This species shows similarities with H. cuneatissima, H. minuticarpa and H. arqueonervosa. Nevertheless, H. uxpanapense differs by being a climbing shrub, with larger internodes on the stem, larger inflorescences and a greater number of white flowers per inflorescence.Conclusions: Hoffmannia uxpanapense belongs to a group of endemic species of Mexico (H. cuneatissima, H. minuticarpa and H. arqueonervosa), and this new taxon is considered as endemic of the southern zone of Veracruz and Oaxaca. |

Antecedentes y Objetivos: La revisión de especímenes de herbario de Hoffmannia (Rubiaceae) y las intensivas exploraciones por los autores originaron el descubrimiento de nuevas especies de este género. Se describe e ilustra a Hoffmannia uxpanapense Cast.-Campos y Bautista-Bello como una nueva especie del sur de México, colectada en la selva alta perennifolia de Uxpanapa en Veracruz y Oaxaca.Métodos: Se revisaron los ejemplares del género Hoffmannia para el estado de Veracruz, se elaboró una matriz de datos morfológicos y se llevó a cabo un análisis de conglomerados para diferenciar a las especies y detectar sus similitudes.Resultados clave: Los ejemplares identificados como “H. wendtii” presentaron caracteres morfológicos diferentes a las especies ya descritas en este género. Dado que este nombre no ha sido publicado, se consideró como una especie nueva aún por describir formalmente. Este taxon muestra similitudes con H. cuneatissima, H. minuticarpa y H. arqueonervosa. Sin embargo, H. uxpanapense difiere por ser un arbusto trepador, con entrenudos del tallo más largos, inflorescencias más grandes y un mayor número de flores de color blanco por inflorescencia.Conclusiones: Hoffmannia uxpanapense se integra a un grupo de especies endémicas de México (H. cuneatissima, H. minuticarpa y H. arqueonervosa), y se considera a este nuevo taxon como endémico de la zona sur de Veracruz y Oaxaca.
