Taxonomic treatments for species complexes are a continuing challenge, in which new information and further questions are constantly being formulated. Regarding the Chromolaena congesta complex, recent studies with morphological data, geographic distribution and climatic niche have shed light on needed changes in the recognition and identification...
The studies on Calea subg. Meyeria (Neurolaeneae, Asteraceae), a group from open vegetation in Southeastern South America, recently resulted in the description of novel species and nothospecies. Continued progress on the nomenclatural and taxonomic studies of this subgenus is presented here. A comprehensive bibliography for species described in thi...
Lepidaploa urceolata is a new, critically endangered species from the upper montane, semideciduous, seasonal forest and scrub vegetation of the Caparaó mountain range, in Southeastern Brazil. The new species is recognised mainly by its strongly bullate leaves, urceolate involucre, involucral bracts with a deflexed apex, inner bristles of pappus wit...
Asteraceae is highly diverse in the Atlantic Forest, especially in montane environments. The early-diverging tribes within Asteraceae are of particular interest because of their great representation in Brazil and unique features within the family. Thus, a floristic inventory and systematic treatment of these basal grade in Caparaó National Park, an...
Molecular phylogenetic reconstruction of Calea demonstrated that the circumscription of infrageneric groups should be altered or that the description of new sections and series is necessary for recognition of monophyletic taxa. One of these infrageneric groups is C. ser. Candolleanae, newly proposed here. Previously recognized as an informal comple...
Asteraceae is the world’s richest plant family and is found on all continents, in environments ranging from the coast to the highest mountains. The family shows all growth forms and, as in other angiosperm families, species richness is concentrated in tropical regions. South America has the highest diversity of Asteraceae in the world, yet taxonomi...
Calea comprises 159 species characterized by striate phyllaries, pistillate ray florets, yellow corolla, and pappus elements as scales. The “Calea teucriifolia complex” is an informal group of 15 species. Molecular phylogenetic inference recognized the polyphyly of this group, but also supports the recognition of a monophyletic subgenus when consid...

Heterocarpy occurs when a plant produces fruits of more than one distinct shape. This phenomenon may result in different dispersion, dormancy, and germination, enabling survival in diverse environmental conditions. Heterocarpy is common in Asteraceae, and one of its most extreme examples occurs in Heterocypsela H.Rob. However, the difference betwee...
The Atlantic Forest is the most species rich vegetation in Brazil and holds several phytophysiognomies, including the vegetation on inselbergs, which is a very stressful xeric environment that selects for very specialized biota. Cololobus is an endemic genus from Atlantic Forest inselbergs of eastern Brazil, and Cololobus ruschianus is a new specie...

Palynological data have been used in Vernonieae for generic and specific delimitations, particularly in the Lepidaploinae subtribe. For this reason, pollen studies in the genus Lepidaploa are important to solve taxonomic conflicts. We characterized 23 species of Lepidaploa searching for morphological differences among themselves. We then compared t...
The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
