Three new species of Mimosa sect. Mimosa ser. Mimosa subser. Polycephalae (Leguminosae, Mimosoideae) are described and illustrated. Mimosa canastrensis, Mimosa chrysothrix, and Mimosa decumbens are all from the campos rupestres of Minas Gerais, Brazil. Discussions about the distributions, habitat, and phenology of the species are provided, in addition to comparisons with similar taxa. 
A new species of Mimosa (Leguminosae) from Brazil
A new species of Mimosa is described from the Atlantic Rainforest and ecotone with the Cerrado of southeastern Brazil, in the states of Minas Gerais, Rio de Janeiro and Sao Paulo, which shares morphological affinities with this species but differs in having porrect-stellate trichomes, a new type of trichome for the genus.

Assessing Chemical Constituents of Mimosa caesalpiniifolia Stem Bark: Possible Bioactive Components Accountable for the Cytotoxic Effect of M. caesalpiniifolia on Human Tumour Cell Lines
The phytochemical and biological study of M. caesalpiniifolia stem bark revealed a new alternative source of antitumour compounds, possibly made effective by the presence of betulinic acid and by chemical co-synergism with other compounds.
