Nepenthes macrophylla

Encyclopedia : N : NE : NEP : Nepenthes macrophylla

Nepenthes macrophylla (Latin: macro = large, phylla = leaves) is a species of pitcher plant and a type of carnivorous plant belonging to the family Nepenthaceae, known only from a very restrictive elavation on Mount Trus Madi in Sabah, Malaysian Borneo. It is an ultrahighland mountain plant requiring cool temperatures with high humidity at night. N. macrophylla was once thought to be a form and subspecies of N. edwardsiana, but is much larger than that species (although its pitchers are smaller). The pitchers can be up to 28 cm high and bear an impressive spiked peristome.
