. Textbook of botany. Botany. 238 TEXTBOOK OF BOTANY is always a drop of thick liquid that glistens in the sun like dew. If an insect alights on the upper surface of the leaf, touching some of the hairs, it is caught in this sticky liquid. The touch of the insect serves as a stimulus to the leaf, which becomes curved, and the hairs bend over from all sides upon the insect. The soft parts of the insect's body are then digested by enzyms contained in the sticky secretion. " Venus' fly-trap " (Fig. 144) has a leaf-blade of two parts, separated by the midrib; the two parts fold together
