A synopsis of Braunia (Hedwigiaceae, Bryopsida) in Mexico, with the lectotypification of Braunia andrieuxii
Background and Aims: Four species of Braunia are known in Mexico: Braunia andrieuxii, B. secunda, B. squarrulosa and B. plicata. A taxonomic study of the species of Braunia in Mexico has not been undertaken before. Moreover, among several “Andrieux” specimens currently available, there is no certain...

| description | Background and Aims: Four species of Braunia are known in Mexico: Braunia andrieuxii, B. secunda, B. squarrulosa and B. plicata. A taxonomic study of the species of Braunia in Mexico has not been undertaken before. Moreover, among several “Andrieux” specimens currently available, there is no certainty as to which particular collection is the type.
Methods: The four species of Braunia known in Mexico and neighboring areas in the southern United States of America, Central America and the Caribbean Islands were studied together for the first time. Based on over 450 collections from several herbaria, a taxonomic treatment and a key to the species of Braunia in this geographical region are presented.
Key results: The four species are described and illustrated. A specimen Andrieux 23 located at BM is selected as the lectotype for B. andrieuxii, with isolectotypes in the herbaria BM and NY. A key is provided for the identification of the species of Braunia in Mexico, and neighboring USA, Central America, and the Caribbean.
Conclusions: Morphological features most likely to be informative for the distinction of the four species in Mexico are the leaf margins, leaf apices, upper leaf cells, and sporophytes. The leaf apex is hyaline and dentate only in B. plicata, while it is concolorous and entire or scabrous in the other three species of Braunia from Mexico. The upper leaf cells are quadrate to short-rectangular in B. andrieuxii and B. plicata; whereas the upper leaf cells are elongate in B. secunda and B. squarrulosa. |

Antecedentes y Objetivos: Se conocen cuatro especies de Braunia en México: Braunia andrieuxii, B. secunda, B. squarrulosa y B. plicata. Anteriormente no se había realizado ningún estudio taxonómico de las especies de Braunia en México. Además, entre varios especímenes colectados por “Andrieux” disponibles, no hay certidumbre sobre cual ejemplar en particular es el tipo. Métodos: Las cuatro especies de Braunia conocidas en México y áreas vecinas en el Sur de Estados Unidos de América, Centroamérica y las islas del Caribe se estudiaron juntas por primera vez. Con base en más de 450 especímenes de varios herbarios, se presenta un tratamiento taxonómico y una clave para las especies de Braunia en esta región geográfica. Resultados clave: Se describen e ilustran las cuatro especies. Se selecciona como lectotipo para B. andrieuxii el ejemplar Andrieux 23 localizado en el herbario BM, con isolectotipos en los herbarios BM y NY. Se provee una clave para la identificación de las especies de Braunia en México, el sur de los EUA, Centroamérica y el Caribe. Conclusiones: Los atributos morfológicos más probables que sean informativos para la distinción de las cuatro especies en México son los márgenes de la hoja, los ápices foliares, las células foliares superiores y los esporofitos. El ápice foliar es hialino y dentado solo en B. plicata, mientras que el ápice es verde y entero o escabroso en las otras tres especies de Braunia en México. Las células foliares superiores son cuadradas a corto-rectangulares en B. andrieuxii y B. plicata; mientras que las células superiores son alongadas en B. secunda y B. squarrulosa.
