Nepenthes rajah (Tam., Borneo) (CITES)
Short supply (FAQ)
Nepenthes rajah forms large, urn-shaped lower pitchers, up to 35 cm high and 18 cm in diameter. The large pitcher lid and the strongly serrated peristome, which looks like a crown, are particularly striking. The pitchers are reddish purple with a purple peristome and red lid, the leaves are peltate.
As with N. lowii, N. rajah is known to be mutualistic with small mammals that use the pitchers as a toilet. However, due to the size of the pitchers, the animals can fall prey to the pitchers themselves.
Nepenthes rajah grows on Mt. Kinabalu and Mt. Tambuyukon, where they colonize mineral soils at 1500-2650 m.a.s.l..
Besides Nepenthes khasiana, Nepenthes rajah is the only species at the highest CITES conservation status (WA I). However, through in vitro propagation in the laboratory, the plants offered here are completely safe to acquire and help the spread of the species in the hobby.
