mimosa. Mimosa is from the Greek “to mimic,” in allusion to the sensitive collapse of the leaves in some species of this tree, which were thought to be mimicking the motions of ani- mals at one time. The mimosa’s reaction to shock or cloudy weather is one of the strangest cases of physiological response among plants, its leaflets folding up face to face at the slightest irritation and its leaves collapsing entirely if the shock is sufficient. |
