Sundew \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}.
