Droseraceae
The Droseraceae are a family of flowering plants. The family is also known as the sundew family. ==Characteristics== The Droseraceae are a small family of carnivorous plants, which consist of three extant genera: ''Drosera'', ''Dionaea'', and ''Aldrovanda'', each with distinct morphologies. The bulk of the members of Droseraceae are contained in ''Drosera'', the true sundews; ''Dionaea'' and ''Aldrovanda'' both have only one extant species. Members of ''Drosera'' 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; however, ''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.
