Sun Dew, the Round Leaved, Red-Rot, or Youthwort, Dro-Sera Rotundifolia, L. an indigenous perennial, growing in mossy bogs, and flowering in the months of July and August. The whole of this singular plant is acrid, and its juice is sufficiently caustic to erode corns, or warts ; and, if it be properly diluted with milk, it forms a safe remedy for removing freckles, and similar blemishes of the skin. Any part of this vegetable coagulates milk, in a manner similar to that of the Common Butter-wort ; and it is likewise supposed to occasion the rot in sheep. On the other hand, the growth of the Youth wort, in particular situations, affords an useful guide in digging for turf.
