![]() ![]() The traps may have nectaries, bright colors, or a flower-like scent to attract prey. The other carnivores with pitfall traps have highly modified leaves where each leaf is a separate trap. Prey slip down the leaves into the pool at the base and drown. The Bromeliad carnivores ( Brocchinia and Catopsis) are the simplest pitfall traps where the base of the whorl of leaves seal to form a cup to catch water. Pitfall traps are leaves modified into pit-like structures. The tentacles as well as the glands on the leaf suface absorb the nutrients from the prey. They snag prey, move to bring as many tentacles as possible into contact with the prey and smother it in slime, and release digestive enzymes. Roridula relies on assassin bugs to do its digestion. Except for Roridula they have separate glands on the leaf surface that secrete digestive enzymes in a thinner mucilage. Drosophyllum, Roridula, Triphyophyllum, and Byblis tentacles do not move and function purely as a trapping mechanism. ![]() The thinner mucilaginous tentacles of Byblis and Drosera function well in damp boggy environments. The resinous mucilage of Drosophyllum, Roridula, and Triphyophyllum works well in dry and extremely wet environments. The adhesive trap leaves with tentacles are similar in function to the flypaper-like leaves except tentacles provide a longer grasp to snag any passer-by. The glands are stalked so the leaf itself doesn't smother in slime while it waits for a prey. The flypaper-like leaves of Pinguicula have specialized short stalked glands that secrete a sticky mucilage that traps small creatures. The simplest trapping mechanism is the adhesive trap. Some complex traps have multiple mechanisms. Pigeon trap ( Genlisea, Sarracenia psittacina).Lobster pot ( Darlingtonia, Sarracenia psittacina).Covered or no pool of water (most Sarracenia, Darlingtonia). ![]() Open with pool of water ( Nepenthes, Heliamphora, Cephalotus, Brocchinia, Catopsis, Sarracenia purpurea and S.Fixed tentacles ( Byblis, Drosophyllum, Roridula, Triphyophyllum).Carnivorous plants have six basic trapping mechanisms (with representative genera or species): ![]()
