A new species of Rogiera (Rubiaceae) of the arid zone of Metztitlán, Hidalgo, Mexico
Background and Aims: The number of species in the genus Rogiera is debatable, varying from 11 to 20 depending on the author. Mexico is undoubtedly the center of diversity for the genus, having up to 14 recognized species, the majority growing in cloud forest and tropical rain forest habitats.Methods...

| description | Background and Aims: The number of species in the genus Rogiera is debatable, varying from 11 to 20 depending on the author. Mexico is undoubtedly the center of diversity for the genus, having up to 14 recognized species, the majority growing in cloud forest and tropical rain forest habitats.Methods: Botanical material collected as part of a floristic and phytogeographic study from the northwest portion of the Metztitlán municipality, Hidalgo, was compared to specimens of Rogiera deposited in the collections ENCB, F, FCME, MEXU and MO. After reviewing all the type material and protologues of all the Rogiera species, we determined that the material represents a new, undescribed species.Key results: Rogiera metztitlensis is described and illustrated as a new species from the arid region of Metztitlán, Hidalgo, Mexico. This new species is morphologically similar to Rogiera amoena, R. cordata and R. ehrenbergii due to the mature stipule orientation (except en R. ehrenbergii) and flower size and color. It differs in being a shrub up to 1 m tall, its smaller stipules 3-4 mm long, the corolla throat with a densely white hairy ring and the wingless seeds.Conclusions: Rogiera metztitlensis is endemic to Hidalgo, where it occurs in arid matorral habitats, in contrast to the humid habitats of other Rogiera species. |

Antecedentes y Objetivos: El número de especies del género Rogiera aún es debatible, varía entre 11 y 20 dependiendo de los criterios utilizados por diferentes autores en su delimitación. México está considerado como el centro de riqueza de este género con hasta 14 especies reconocidas que se distribuyen principalmente en bosque mesófilo de montaña y selva alta perennifolia.Métodos: El material botánico colectado como parte de un estudio florístico y fitogeográfico de la porción noroeste del municipio Metztitlán, Hidalgo, se comparó con ejemplares de especies de Rogiera depositados en las colecciones ENCB, F, FCME, MEXU y MO. Después de revisar los tipos nomenclaturales y protólogos de todas las especies de Rogiera, se determinó que este material corresponde a una especie nueva.Resultados clave: Se describe e ilustra Rogiera metztitlensis, una especie nueva de la zona árida de Metztitlán, Hidalgo, México. Esta especie tiene similitud morfológica con Rogiera amoena, R. cordata y R. ehrenbergii en la orientación de la estípula al madurar, (excepto en R. ehrenbergii) tamaño y color de las flores. Difiere de éstas por ser un arbusto de hasta 1 m de alto, las estípulas más pequeñas, de 3 a 4 mm de largo, la garganta de la corola con anillo de tricomas blancos y las semillas sin alas.Conclusiones: Rogiera metztitlensis es endémica de Hidalgo, se desarrolla en hábitats áridos, en contraste con los hábitats húmedos en los que predomina el resto de las especies de este género.
