The new discovery measures up to 30 centimeters in diameter and is formed by a tendril which inflates into a large cup-shaped trap. McPherson told CNN: "Around the mouth of the pitcher are secretions of nectar which attracts insects and small animals. The rim has lots of waxy downward-pointing ridges which help prey fall directly into the pitcher.
"These plants grow in really harsh areas where soil quality is very poor -- often pure gravel or sand. Catching insects allows the plant to augment nutrients that it otherwise wouldn't have access to." "These plants have evolved to catch insects. But on rare occasions they do catch rats and mice. The first reports of these plants catching rats was made in the 19th century by a British explorer called Spenser St John," McPherson said.
This is very interesting for those people who see a very clear separation between vegetarian and non-vegetarian food. If a plant can itself eat meat, then that separation starts to wither away.
