Section Mimadenia: Its phylogenetic relationships within the genus Mimosa (Leguminosae, Mimosoideae) using plastid trnLF sequence data

Mimosa L. includes more than 530 species and is subdivided into five sections, including Mimadenia Barneby, Batocaulon DC., Habbasia DC., Calothamnos Barneby and Mimosa. It has previously been proposed that Mimosa is derived from piptadenioid ancestors and that section Mimadenia is a morphological g...

We report a phylogenetic analysis of chloroplast nucleotide sequences of the trnL intron and the trnLtrnF intergenic spacer from 36 species of Mimosa, and six related genera. Our analysis indicated that genus Mimosa is monophyletic, and the species of section Mimadenia constitute a clade sister to the rest of the genus. Although section Mimadenia, as described by Barneby (1991), seems to be monophyletic, the remaining sections Barneby (1991) proposed are not resolved as monophyletic. An effort needs to be made towards a new infrageneric classification of Mimosa that considers the phylogenetic evidence. © 2011 CSIRO. Fil:Bessega, C. Universidad de Buenos Aires.
