Mimosa somnians, commonly known as dormideira, is a species of woody shrub in the genus Mimosa and the family Fabaceae. It is native to the Caribbean, Central America and South America.[2] It is a short, low-lying shrub with minuscule thorns lining its stem-like hairs.[3]

Mimosa somnians is notable for exhibiting rapid plant movement. Its leaves are sensitive to tactile stimulus, folding quickly when touched, similar to Mimosa pudica.[4] It can be differentiated from Mimosa pudica in that its leaves are bipinnate, there are more than four subbranchlets and these originate from more than one point on the branch.[4]

Mimosa somnians's leaflets are 4–5 mm long.[3] The flowers form pink balls.[3] It propagates by seeds.[4]
