One of the exquisite tropical wonders of Philippines is its largest pitcher plant Nepenthes attenboroughii which is famous for its large bell shaped upper and lower pitchers. This amazing specie is recorded as producing very large pitchers in the world. This species was named in the honor of Sir David Attenborough who was a natural history broadcaster. This wonderful pitcher plant is found only in the mountain range of Palawan in Philippines.
Apparently, due to its close resemblance with Nepenthes Rajah, it seems a close relative of this pitcher plant of Borneo. Nepenthes attenboroughii was discovered just few years ago in 2007 by Alastair S. Robinson, Stewart R. McPherson and Volker B. Heinrich during a 2 month research expedition to catalogue the different species of pitcher plant found across the Philippine Archipelago.
Nepenthes attenboroughii, the largest pitcher plant of Philippines is a terrestrial upright or scrambling shrub. The stem, which may be up to 3.5 cm thick, is circular in cross section and attains a height of up to 1.5 m. The leaves are coriaceous and sessile or sub-petiolate. The leaves of rosettes are up to 30 cm long and 10 cm wide, whereas those of the scrambling stem are up to 40 cm long and 15 cm wide. The leaves are oblong to elliptic. As it is described earlier , the pitchers of the Nepenthes attenborroughii are very large which create tube-like leaf structures into which insects and other small animals tumble and become trapped. Even the botanists are of the view that the pitchers are so big that they can catch rats as well as insects in their leafy trap.
