Venus’s-Flytrap

 

(Dionaea muscipula), a perennial herbaceous insectivorous plant of the sundew family (Droseraceae). The stem is short, with a rosette of leaves; small white flowers are gathered into a shield on a tall floriferous shoot. The leaves have winged stalks and bilobial oval disks. In the center are three hairs. When an insect agitates them the leaf closes and emits a digestive fluid. Digestion lasts five to ten days, after which the leaf reopens. After the second or third catch, the leaf dies. Venus’s flytraps grow on mossy marshes and the moist sands along the Atlantic coast of North America. In catching insects, they compensate for the lack of nitrogen, phosphorous, and other substances in the infertile soils on which they grow.
