Nepenthes, tropical pitcher plants or monkey cups, are another genus of carnivorous plants with pitfall traps. Nepenthes present a vine-like appearance and are much sought after due to the incredible shapes and colours of the pitchers (cups)
Β There are about 130 species that are wide spread, and can be found in China, Malaysia, Indonesia,Β Philippines, Madagascar, Seychelles, Australia, India,Β Borneo and Sumatra
The nickname βmonkey cupsβ comes from the factΒ that monkeys have often been observed drinkingΒ rain water from themΒ
Most species of Nepenthes are tall creepers (10-15m), with a shallow root system. From the stem youΒ will often see sword like leaves growing, with aΒ tendril (often used for climbing) protruding from theΒ tip of the leaf
At the end of the tendril, the pitcher forms first as a small bulb, which then expands and forms the cup. The trap contains fluid, produced by the plant, which may be watery or syrupy and is used to drown and digest the insects
The lower part of the cup contains glands that absorb and distribute nutrients. Most of these plants are small and tend to trap only insects, but some larger species, such as Nepenthes Rafflesiana and Nepenthes Rajah, have been documented to catch small mammals like rats
