DescriptionThree families of "carnivorous" plants are found in New England's nutrient-impoverished bogs and peatlands; they obtain nitrogen and other nutrients by trapping and digesting insects and other small organisms. The pitcher plant is an insectivorous, evergreen, perennial herb. Its modified leaves form a water-filled pitcher, drowning insects that are lured into it. The leaves consist of five insect-trapping sections. The top of the leaf, or mouth of the pitcher, forms a hood that attracts insects by means of nectar glands and bright red venation. Next, the inside rim is lined with stiff, downward-pointing hairs and exudes a secretion that numbs the insect, so that climbing out is all but impossible. The third section is a slippery slide, where plant cells stick to the insects' legs, propelling them into the watery pitcher, where digestive enzymes and bacteria dissolve the soft parts of the insects which are absorbed into the plant. Indigestible parts accumulate in the last section -- a long, narrow stalk at the base of the leaves, which also directs nutrients to the roots and flower. Several species of insects and arthropods actually inhabit the pitcher plant without being digested.
