Systematics and Evolution of Syncephaly in American Vernonieae (Asteraceae) with Emphasis on the Brazilian Subtribe Lychnophorinae
TLDR
Results show that syncephaly has been historically used to delimit the subtribe Lychnophorinae, and that this character probably appeared independently three or four times in the evolution of American Vernonieae. Expand
Functional groups in Lychnophorinae (Asteraceae: Vernonieae) based on morphological and anatomical traits
TLDR
The Lychnophorinae subtribe occurs mainly on the Central Brazilian Plateau, especially in areas characterised by intense solar radiation, large daily temperature fluctuations, water scarcity during autumn and winter, and frequent fire. Expand
The Lucilia group (Asteraceae, Gnaphalieae): phylogenetic and taxonomic considerations based on molecular and morphological evidence
TLDR
Morphology and molecular analyses combined showed that the traditional generic circumscription of most of the genera correlates with the inferred phylogenetic relationships, and suggest that the Lucilia group is paraphyletic, since Antennaria, Chionolaena, Gamochaeta, Loricaria, Micropsis, Mniodes and Stuckertiella are all nested within theLucilia group. Expand
A new species of Chresta (Vernonieae, Asteraceae) endemic to the Mata Atlântica Domain, Brazil
TLDR
This is the first record of a species of Chresta endemic to a phytogeographic domain other than the Cerrado and Caatinga , since those outcrops are included in the Mata Atlântica Domain (Atlantic Forest). Expand
Taxonomic novelties in Eremanthus (Compositae: Vernonieae) from Brazil
TLDR
A new species of Eremanthus (Asteraceae: Vernonieae), E. brevifolius, endemic to Minas Gerais State, is presented and its affinities assessed. Expand
Taxonomic novelties in Chamaecrista (Leguminosae: Caesalpinioideae) from Brazil
TLDR
Three former varieties are recognized at the specific level, two new combinations and one synonymization are here proposed and the geographic distribution and taxonomic affinities of these species are discussed. Expand
Phylogenomics Yields New Insight Into Relationships Within Vernonieae (Asteraceae)
TLDR
This study presents the first attempt at studying the phylogeny of Vernonieae using phylogenomics with high support recovering approximately 700 nuclear markers obtained through target capture. Expand
NEW NAMES IN VERNONIEAE (ASTERACEAE) OF NORTHEASTERN BRAZIL
The monotypic genera Irwinia G.M. Barroso, Oiospermum Less., and Pithecoseris Mart. ex DC. are considered synonyms, respectively, of Blanchetia DC., Centratherum Cass., and Chresta Vell. ex DC.,Expand
Comprehensive untargeted metabolomics of Lychnnophorinae subtribe (Asteraceae: Vernonieae) in a phylogenetic context
TLDR
The results confirm that data generated using metabolomics provide evidence for chemotaxonomical studies, especially for phylogenetic inference of the Lychnophorinae subtribe and insight into the evolution of the secondary metabolites of this group. Expand
A Phylogenetic Analysis of Lychnophorinae (Asteraceae: Vernonieae) Based on Molecular and Morphological Data
TLDR
Biogeographic reconstruction suggests that the diversification and expansion range of most Lychnophorinae clades in the campos rupestres, from an ancestor in tropical seasonl forests, occurred previously to the conquest of the cerrado s. Expand
