Mimosa somnians ("Dormideira") is a tree in the Fabaceae family. It is native to the Caribbean, Central America and South America.[3] It is a short, low-lying shrub with minuscule thorns lining its stems like hairs.[4] Its leaves are sensitive, meaning that, when touched, they close quickly, similarly to Mimosa pudica.[5] 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.[5]

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