 Sun·dew n. Bot. Any plant of the genus Drosera, low bog plants whose leaves are beset with pediceled glands which secrete a viscid fluid that glitters like dewdrops and attracts and detains insects. After an insect is caught, the glands curve inward like tentacles and the leaf digests it. Called also lustwort.
