Droseraceae (sundews) A family of insectivorous herbs in most of which the leaves are borne in rosettes bearing glandular hairs which secrete protein-digesting enzymes so that the soft parts of insects trapped on the sticky leaves are digested and absorbed. The plants occur mostly in boggy places or on poor, acid, stony soils, and they may benefit from extra mineral nutrients obtained from the insect bodies. The flowers are regular, in 1-sided cymes. There are 4 genera, with about 85 species, with a cosmopolitan distribution.
