The subtribe Plucheinae (Inuleae, Asteraceae) in Mexico: taxonomy, diversity, and distribution Autores: Redonda Martínez, Rosario

“…The aim of this work is to present an updated taxonomic study of the Mexican Plucheinae, including identification keys and descriptions of genera and species.Methods: A revision of floristic-taxonomic works of the tribes Inuleae and Plucheeae was carried out to generate a list of species present in Mexico, which was compared with the collections of Mexican herbaria ENCB, FCME, IEB and MEXU, in addition to online herbaria from the United States of America.Key results: In Mexico, Pluchea is the genus of the subtribe Plucheinae with the widest diversity and distribution, grouping eight species and two infraspecific categories, being found in 27 states. Oaxaca and Veracruz concentrate the highest number of species, and the least diversity is found in Aguascalientes, Mexico City and Durango, where only one taxon is registered. …”
