Росянковые (Droseraceae) 8/1/13—5/15/17
Droseraceae is a family of flowering plants. The family is also known as the sundew family. It is a small family of carnivorous plants, which consist of approximately 180 species in three extant genera:
Most of the members of Droseraceae are contained in Drosera, the true sundews. Both Dionaea and Aldrovanda have only one extant species. Droseras secrete a sticky substance from their leaves that traps prey. Dionaea and Aldrovanda both use snap-traps that close rapidly when the leaves are disturbed, Dionaea is terrestrial, while Aldrovanda is strictly aquatic. Like carnivorous plants of other families, the Droseraceae are able to supplement their nutrient intake, especially that of nitrogen, by capturing and digesting small animals such as insects. In this way, these plants are able to thrive in nutrient-deficient areas, such as sphagnum bogs.
