Named in honor of the renowned naturalist Sir David Attenborough, this species is native to the Victoria massif in Palawan, Philippines. Nepenthes attenboroughii is critically endangered due to habitat destruction and illegal collection. With a unique pitcher shape and size, it holds a special place in Nepenthes, but its rarity and vulnerability make its conservation of utmost importance. Efforts are being made to protect and preserve this remarkable species from extinction.
