Explanation: Insectivorous plants of India:

  • Drosera or Sundew: inhabiting wet infertile soils or marshy places. The tentacles on the leaves secrete a sticky fluid that shines in the sun like dewdrops. Therefore, the Drosera are commonly known as ‘sundews. When an insect lured by these glistening drops alights on the leaf surface it gets stuck in this fluid and are absorbed and digested.
  • Aldrovanda: is a freefloating, rootless aquatic plant, the only species found in India, occurs in the salt marshes of Sunderbans, south of Calcutta. It also grows in fresh water bodies like ponds, tanks and lakes.
  • Nepenthes: The members of the family are commonly known as ‘pitcher plants’ because their leaves bear jar-like structures.
