Other information [Source: Wwikipedia]
Nepenthes rafflesiana (pronounced /nɨˈpɛnθiːz ræˌfliːziˈɑːnə/, after
Stamford Raffles), or Raffles' Pitcher-Plant, is a species of pitcher
plant. It has a very wide distribution covering Borneo, Sumatra,
Peninsular Malaysia, and Singapore. N. rafflesiana is extremely
variable (second only to N. mirabilis) with numerous forms and
varieties described. In Borneo alone, there are at least four distinct
varieties. The giant form of this species produces enormous pitchers
rivaling those of N. rajah in size.
Nepenthes rafflesiana is a very widespread lowland species. It is
common in Borneo and parts of the Riau Archipelago, but has a
restricted distribution in both Peninsular Malaysia and Sumatra. It is
only widespread in the southeastern region of the Malay Peninsula,
particularly in the state of Johor, where it is relatively abundant.
N. rafflesiana has only been recorded from the west coast of Sumatra,
between Indrapura and Barus.
N. rafflesiana generally occurs in open, sandy, wet areas. It has been
recorded from kerangas forest, secondary formations, margins of peat
swamp forest, heath forest, and seaside cliffs. It grows at elevations
ranging from sea-level to 1200 m or even 1500 m.
Most wild populations of Nepenthes, including N. rafflesiana, are
endangered due to habitat destruction and (to a lesser extent)
poaching. N. rafflesiana is currently listed as a CITES Appendix II
plant, so it does have some international trade restrictions (though
not an outright ban). Today, most N. rafflesiana plants on the market
are propagated by plant tissue culture or other forms of vegetative
propagation. When purchasing any plant, especially those protected by
CITES, it is important to ask the vendor about the plant's provenance.
