Plants that obtain some or most of their nutrients by trapping and consuming insects, protozoans and other animals are called carnivorous plants. These plants arc though widespread but arc rather rare. They arc mostly restricted to habitats such us bogs where soil nutrients are extremely limiting. The leaves of these plants are used not only for photosynthesis but also in trapping prey. The present book makes an elaborate experimental study on various mechanisms of carnivorous plants : structure, movement of tentacles, aggregation of protoplasm, effects of heat, nitrogenous and non-nitrogenous fluids, salts, acids, alkaloids and other poisons, and vapours, sensitiveness and transmission of motor impulse. Basing the presentation on the common sundew, the book also describes various species such as Dionaeu Muscipula, Aldrovanda Vesiculosa, etc. The book also makes an interesting presentation on various species of Drosophyllum, Pinguicula and Utricularia. This experimental study on various mechanisms of carnivorous plants will be highly useful studies in botany, researches, commercial growers and general readers.
