Mimosa somnians ("Dormideira") is a tree in the Fabaceae family. It is native to the Caribbean, Central America and South America.[2] It is a short, low-lying shrub with minuscule thorns lining its stems like hairs.[3] Its leaves are sensitive, meaning that, when touched, they close quickly, similarly 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 sominans's leaflets are 4–5 mm long.[3] The flowers form pink balls.[3] It propagates by seeds.[4]
