Taxonomic treatment of the tribe Mutisieae (Asteraceae) in Mexico
Background and Aims: The tribe Mutisieae includes 14 genera and about 200 species distributed mainly in South America; it comprises several taxa of Asteraceae with bilabiate corollas and heterogamous heads with trimorphic or dimorphic florets. The aim of this work is providing an updated taxonomic t...

| description | Background and Aims: The tribe Mutisieae includes 14 genera and about 200 species distributed mainly in South America; it comprises several taxa of Asteraceae with bilabiate corollas and heterogamous heads with trimorphic or dimorphic florets. The aim of this work is providing an updated taxonomic treatment of the tribe in Mexico.Methods: A bibliographic review of several taxonomic studies of the Mutisieae genera present in Mexico was carried out, and online collections and some scientific collections were consulted, in order to generate the list of Mexican Mutisieae as well as identification keys and descriptions of members of the tribe.Key results: In Mexico, the tribe Mutisieae is represented by four genera and 16 species, nine of which are endemics. Chaptalia is the most diverse with 12 species, followed of Leibnitzia with two, while Adenocaulon and Gerbera are represented by one taxon each one.Conclusions: The specific richness of Mutisieae in Mexico is limited; however, the endemism level is considerable, as the nine taxa restricted distribution to the country represent 56.25% of total Mexican Mutisieae. The 12 species of Chaptalia are equivalent to 30% of the genus; the seven endemic taxa correspond to 58.33% of the diversity of the tribe, which occurs in the national territory. |

Antecedentes y Objetivos: La tribu Mutisieae incluye 14 géneros y alrededor de 200 especies que se distribuyen principalmente en Sudamérica; agrupa varios taxones de asteráceas con corolas bilabiadas y cabezuelas heterógamas que contienen flores trimórficas o dimórficas. El objetivo de este trabajo es presentar un tratamiento taxonómico actualizado de la tribu en México.Métodos: Se realizó una revisión bibliográfica de trabajos taxonómicos de los géneros de Mutisieae presentes en México, se consultaron colecciones físicas y en línea de diversos herbarios, y portales electrónicos con la finalidad de generar la lista de especies mexicanas, claves de identificación y descripciones de los miembros mexicanos de esta tribu.Resultados clave: En México, la tribu Mutisieae incluye cuatro géneros y 16 especies, de las cuales nueve son endémicas. Chaptalia es el más diverso con 12, seguido de Leibnitzia con dos, mientras que Adenocaulon y Gerbera están representados por un taxon cada uno.Conclusiones: La riqueza específica de Mutisieae en México es baja; sin embargo, el endemismo es considerable dado que los nueve taxones con distribución restringida al país representan 56.25% del total de las Mutisieae mexicanas. Las 12 especies de Chaptalia equivalen a 30% del género; los siete taxones endémicos corresponden a 58.33% de la diversidad de la tribu, que ocurre en el territorio nacional.
