Extract

It is a well known fact that certain plants, as Sliene antirrhina, L., and allied species, exude a sticky, viscid substance of stalk or peduncle for the purpose of preventing ants, small beetles, and other honey-loving intruders, which are too small to aid effectively in fertilization, from creeping up to the flower and robbing the honey-glands of their precious nectar. Other plants, as the Sundews, Drosera rotundifolia, L. etc., excrete a smiliar substance with which they attact insects, which are caught and afterwards utilized as food by the plant.
