Resumen:
Among the Nyctaginaceae Mirabilis is characterized by having cymose
inflorescences and involucres of 5 connate bracts and acrescent in
fruit, underlying 1-3 flowers. With 55-57 species, it is one of the most
diverse genera in the family. The aim of this work is to analyze the
diversity ofMirabilis in Mexico, presenting the taxonomic treatment of
the species, an identification key, habitat and phenology data, and
their distribution maps. Synonymy is presented and a lectotype for
Mirabilis aggregata, M. sanguinea and M. urbani are designed. According
to the studied specimens and data analyzed, Mexico is the country with
the greatest diversity of the genus with 31 species, of which 14 are
endemic. Mirabilis glabrifolia, M. jalapa and M. viscosa have the
largest distribution, while M. calophlebia, M. hintoniorum, M. nesomii
and M. urbani are the most restricted. Most species are found in
xerophytic scrubland and tropical deciduous forest; at biogeographic
provinces level, these are mainly found either the North Plateau
(Chihuahuense), South unpland and Pacific Coast. M. melanotrichia is the
species found at the highest altitude.
