A young pitcher, probably a lower pitcher rafflesiana species which is characteristically round and squat, with distinct hairy ‘winged’ fringe. The peristome and lid are not yet formed. This one hasn’t had its first meal of insect! Photographed in the garden next to the office / canteen at Kipandi Butterfly Park.

nepenthes platychila

Nepenthes platychila at Kipandi Butterfly Park.

Nepenthes are seldom given common names. The species platychila is endemic to the Hose Mountains of central Sarawak. This one was photographed in a conservation nursery at Kipandi Butterfly Park. {Name taken from ID tag on the plant.}

Generally, nepenthes is a genus of passive carnivorous tropical pitcher plant. The pitcher is a bizarrely modified part of a leaf. There are no movable parts. Insects are attracted by sweet-tasting nectar on the peristomes. Once inside, they are unable to climb the slippery wall of the pitcher. The insect drowns and its body is digested by juices secreted into the water held in the pitcher.

There are 82 known species of nepenthes worldwide. They can be found in the moist tropics. The Island of Borneo is the centre of the nepenthes diversity with more than 30 species.

The N. Rafflesiana is a widespread lowland species common in Borneo but has a restricted distribution in Peninsular Malaysia and Sumatra. It likes open, sandy wet areas. It can be found at sea level and also at elevations up to 1,500 metres. It produces two distinct types of pitchers (modified leaves). The lower pitchers are generally round and squat, with ‘winged’ fringes. The upper pitchers are narrow at their base.

The species is extremely variable in form and colours. In Borneo alone, there are three varieties; upper pitchers, lower pitchers and the giant pitchers. This specimen above, a lower pitcher, is drying up, but the distinctive ‘winged’ fringe and elongated neck of the peristome is clearly seen. It is a scrambling vine with stems that can climb to 15 metres high. Unlike the Venus flytrap, all nepenthes do no have movable parts and are passive carnivores.
