—Circumscription of genera in the tribe Vernonieae is complex due to overlapping morphological features among genera such as Chrysolaena, Echinocoryne, Lepidaploa, and Lessingianthus. These genera have been segregated from the genus Vernonia s. l.,

The lowlands of mid-latitude South America comprise complex temperate ecoregions characterized by a unique biodiversity. However, the processes responsible for shaping its species diversity are still largely unknown. Turnera sidoides subsp. carnea is

Four populations of Chrysolaena verbascifolia (Vernonieae: Asteraceae) from localities in Argentina were cytologically analysed for meiotic behaviour and pollen viability. This is the first meiotic analysis in the species. All were diploids with 2n =

Vegetative anatomical features are poorly known in the South American genus Chrysolaena. In this study, leaves and stems of six Chrysolaena species were described and compared morphologically and anatomically using diaphanization, microtome serial se

Floral microcharacters of the genus Chrysolaena H. Rob. (Vernonieae, Asteraceae) were analysed in detail for the first time in order to evaluate the taxonomic position of conflictive species in the group. The results were also compared with studies c
