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...
