Drosera - The Carnivorous plant

Members of this genus are called 'sundews'. There are about 150-160 Drosera species described, and they are scattered around the globe. These plants bear stalks or tentacles on their leaves, and these stalks are tipped with glands (which are often brightly coloured). The glands exude attractive nectar, adhesive compounds, and digestive enzymes. Insects that land on the leaves stick fast and are digested. Often nearby glandular tentacles are stimulated and also adhere to the insect, and on many species the entire leaf coils around the prey. These motions are slow, taking minutes or hours to occur.
