Sundew

Sundew, the popular name for the species of the large genus Drosera, the typical genus of the order Droseraceae. There are three British species They have small fibrous roots; rosettes of reddish radical leaves covered with "tentacles," or lobes ending in glands, each of which secretes a glistening dewlike drop of liquid; and a scorpioid, or apparently circinate, inflorescence of minute white flowers, which are generally cleistogamous. The sundews are all carnivorous plants (q.v.), D. rotundifolia having been more thoroughly investigated than any other of these plants. All three British species grow in bogs and moist heaths.
