Nepenthes robcantleyi is believed to be either critically endangered, or possibly even extinct in the wild. The female parent of this release has the cultivar name ‘Queen of Hearts’, and is very probably the most photographed Nepenthes in history, having appeared on many of our gold medal winning Chelsea Flower show exhibits. The male parent named ‘King of Spades’ is darker in overall colouration than the ‘Queen of Hearts’ and has green peristome wings.
For some years we labelled these plants as a form of N. truncata, although there were clearly striking taxonomical differences between them and the existing published description of N. truncata. In December 2011 N. robcantleyi was described in the Nordic Journal of Botany as a distinct species in its own right by Dr. Martin Cheek, a taxonomist with the Royal Botanic Gardens at Kew. The publication gives the history of this species in cultivation and the reason why the3848 name Nepenthes robcantleyi was chosen.
