Trichocline maxima (Compositae, Mutisieae) redescoberta: Taxonomia, lectotipificação, e estado de conservação de uma Asteraceae rara e endêmica do Pampa

Abstract

Trichocline maxima was considered probably extinct but has been rediscovered in northern Uruguay after almost 70 years since its last record in this country. We provide an updated description of the species, an indication of a lectotype and we discuss morphology, axonomy, nomenclature, geographical distribution, and conservation status of the species. An identification key for the species of the genus in Uruguay and Brazil is also presented.
