Mimosa (genus) en

Genus containing around 450 shrubs, undershrubs, climbers, or trees native to tropical and subtropical areas throughout both hemispheres. They are so named from the movements of the leaves in certain species that mimic animal sensibility, including rapidly moving when touched. Certain plants called "mimosa" were formerly assigned to this genus, including Albizia julibrissin (silk tree) and Acacia dealbata (silver wattle).
