Banding and FISH in three species of Vernonia, subsection Macrocephalae (Asteraceae, Vernonieae)
To complement our knowledge about the karyotypes of the genus Vernonia Schreb., different techniques of chromosome banding, including AgNOR, triple staining with fluorochromes CMA/DA/DAPI (CDD), and

Karyotype variation in 11 species of the Vernonieae Cass. tribe (Asteraceae Bercht. & J. Presl)
A comparative analysis of the Vernonieae species was performed to understand the events involved in the chromosome evolution of these species and to further deduce their taxonomy.
Systematic consideration of floral microcharacters of the South American genus Chrysolaena (Vernonieae, Asteraceae)
The results show that related species can be distinguished by the different combinations of floral microchar characters, and the value of microcharacters could be increased if they are combined with other morphological, cytological, and palynological data.
A presente revisao relata a historia taxonomica de Vernonieae Cass., tribo da familia Asteraceae, de ocorrencia pantropical, com provavel origem nas regioes tropicais, sendo apontado o sul do Brasil
Systematic significance of cypsela morphology in Lessingianthus (Vernonieae, Asteraceae)
Cypsela features of Lessingianthus are often widespread in other related genera of Vernonieae, but they are valuable within genera to differentiate related species from one another.
Floral microcharacters in Lessingianthus (Vernonieae, Asteraceae) and their taxonomic implications
Micromorphological characters of 113 species of the South American genus Lessingianthus H.Rob. (Vernonieae, Asteraceae) were analyzed to evaluate their reliability as taxonomic markers. The corolla
Pollen Morphology and Implications for the Taxonomy of the Genus Chrysolaena (Vernonieae, Asteraceae)
The morphology of pollen grains in all 18 species of Chrysolaena is characterized and results show that all the studied species possess pollen grains of type “C”, which is therefore characteristic of the genus.
Cytotaxonomy of some species of the South American genus Lessingianthus (Asteraceae, Vernonieae)
Mitotic chromosome numbers of 32 populations belonging to 23 species of the genus Lessingianthus H.Rob. (Vernonieae, Asteraceae) were determined. The chromosome number of all examined plants was
Vernonia longicuspis (Compositae: Vernonieae), a new combination from Bolivia
SummaryA new combination is provided in Vernonia (Compositae: Vernoniae), V. longicuspis (Dematt.) D. J. N. Hind, based on Lessingianthus longicuspis Dematt., recently described from Bolivia (Santa
