Nepenthes × kinabaluensis , or the Kinabalu Pitcher-Plant, is the natural hybrid between N. rajah and N. villosa. It was first collected near Kambarangoh on Mount Kinabalu, Borneo by Lilian Gibbs in 1910 and later mentioned by John Muirhead Macfarlane as Nepenthes sp. in 1914. Although Macfarlane did not formally name the plant, he noted that [a]ll available morphological details suggest that this is a hybrid between N. villosa and N. rajah. It was finally described in 1976 by Shigeo Kurata as N. × kinabaluensis. The name was first published in Nepenthes of Mount Kinabalu, but was a nomen nudum at the time as it lacked an adequate description and information on the type specimen. The name was subsequently published validly by Kurata in 1984.
