Nepenthes spp.

From My Dad's Garden-Nepenthes spp. -Periuk Kera Nepenthes spp. -Periuk Kera 
This plant was planted by my father just under the Jambu Batu tree in front of our house. It's not that difficult to plant Nepenthes spp. here in Meru since the temperature and air moisture is pretty much the same as the original place where this plant is originated.
"Nepenthes rafflesiana is found in tropical lowlands. It produces two distinct types of pitchers (heavily modified leaves), which are used to capture and kill insect prey for nutrients. The lower pitchers are generally round, squat and 'winged', while the upper pitchers are more narrow at their base. The species is widely variable and comes in a variety of shapes and colors - most contain varying amounts of green, white, and maroon streaks.
All Nepenthes are passive carnivores with no moving parts, unlike their distant cousins the Venus flytrapNepenthes rafflesiana kills by luring its prey into its pitchers, whose peristomes secrete a sweet-tasting nectar. Once the insect is inside, it quickly finds the walls of the pitcher too slippery to scale and drowns. Digestive enzymes released by the plant into the liquid break down the prey and release soluble nutrients, which are absorbed by the plant through the walls of the pitcher. The carnivorous nature of Nepenthes is supposedly a consequence of living in nutrient-poor soils; since the main method of nutrient absorption in most plants (the root) is insufficient in these soils, the plants have evolved other ways to gain nutrients. As a result, the roots of Nepenthes and most other carnivorous plants are slight and fragile; hence care must be taken when repotting. All Nepenthes are dioecious, meaning that each individual plant has only male or female characteristics." Source: Wikipedia
