Systematic consideration of floral microcharacters of the south american genus chrysolaena (vernonieae, asteraceae)
(Taylor and Francis Ltd, 2016)
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 ...
Meiotic behaviour and B chromosomes in Argentine populations of chrysolaena verbascifolia (vernonieae: asteraceae)
(Taylor and Francis Ltd, 2017-01)
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. ...
The genus Lepidaploa (vernonieae, asteraceae) in southern South America
(Magnolia Press, 2018-07-24)
A morphological analysis of the genus Lepidaploa (Vernonieae) of southern South America has been carried out. Until now,
the information concerning the genus was fragmented and incomplete for this region. Altogether, 13 ...
Fruit of lepidaploa (cass.) cass. (vernonieae, asteraceae): anatomy and taxonomic implications
(Sociedade Botânica do Brasil, 2018-10)
Lepidaploa is a taxonomically complex genus of Vernonieae, which is difficult to delimit morphologically due to
vegetative and reproductive characters that overlap with Chrysolaena and Lessingianthus. Anatomical studies ...
Systematic significance of cypsela morphology in Lessingianthus (Vernonieae, Asteraceae)
(Csiro Publishing, 2015-08-07)
The taxonomic significance of cypsela features of South American species of Lessingianthus (Vernonieae,
Asteraceae) is analysed for the first time and discussed in relation to other genera of the tribe Vernonieae. The ...
A new species of lepidaploa (asteraceae: vernonieae) from Minas Gerais State, Brazil
(Magnolia Press, 2016-09-07)
Lepidaploa scintillans is described as a new species from the Minas Gerais State in southeastern Brazil. This new species can
be easily distinguished from other Lepidaploa species by the sericeous, nacreous-argent indumentum ...
DNA content in species of Vernonia and Vernonanthura from South America : an approach to systematics and evolution of the Vernonieae (Asteraceae)
(Taylor & Francis, 2015-11)
There are relatively few studies of DNA content in the Vernonieae (Asteraceae) tribe. The first studies were realized in the Lessingianthus genus and determined the DNA content of 25 species. After DNA content, ploidy level ...
