What is a plant, whose leaves fold inward when touched, called?

Mimosa pudica (also called sensitive plant, sleepy plant, action plant, touch-me-not, shame plant) is a creeping annual or perennial flowering plant of the pea/legume family, often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, defending themselves from harm, and re-open a few minutes later.

The leaflets also close when stimulated in other ways, such as touching, warming, blowing, shaking, which are all encapsulated within mechanical or electrical stimulation. These types of movements have been termed seismonastic movements. This reflex may have evolved as a defense mechanism to disincentivize predators, or alternatively to shade the plant in order to reduce water loss due to evaporation.
