Resumen:
A taxonomic treatment of the genus
Diplolepis
is here presented. Based on molecular and biogeo
-
graphical information recently published, this group is monophyletic and its geographical distribution is
restricted to southwestern South America. The study comprised the analysis of herbarium specimens in
-
cluding nomenclatural types, supplemented with collections and observation of species in the field. This
paper describes the variation in the morphology of the genus, including habit, stems, leaves, inflorescen
-
ce, calyx, corolla, corona, gynostegium, pollinia, fruits and seeds. The morphological and distributional
differences between
Diplolepis
and related genera are discussed. A key to differentiate the species of the
genus is here given. Within each species we provide the valid name, synonyms, description of vegetative
and reproductive morphological characters, geographical distribution, ecology, uses, common names,
phenology, iconography and specimens examined. A lectotype is designated for
D. viridis
.
