Botanists believe they have discovered one of the world's largest carnivorous plants in Southeast Asia.
The giant pitcher plants were located on Mount Victoria in Palawan, central Philippines by a team led by UK botanist Stewart McPherson.
The second largest species, now called Nepenthes attenboroughii, has been named in honor of the UK's world-renowned natural history presenter Sir David Attenborough.
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.
"The pitchers are half full of a liquid consisting of acids and enzymes which help break down its prey."
The insectivorous, sometimes carnivorous diet is crucial for the plants' survival says McPherson.
"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."
