Abstract

A revision of the neotropical genus Paragynoxys of the Asteraceae (tribe Senecioneae) is presented. This group is a distinct entity characterized by a pachycaulous arborescent habit, homogamous discoid capitula, the presence of white corollas with limbs divided to the base, sagittate anthers, and style branches with enlarged conical tips. In the present treatment, 12 species are accepted. Descriptions of the genus and species, a key to species, synonyms, a new combination (Paracalia lopezii, based on Paragynoxys lopezii), and distribution data are presented.
