Due to their dioecious nature, a hybrid involving a pair of "Nepenthes" species can represent one of two possible crosses, depending on which species was the female and which was the male. When the cross is known, the female (or pod) parent is usually referred to first, followed by the male (or pollen) parent. This is an important distinction, as the hybrid will usually display different morphological features according to the type of cross; the pod parent is thought to be dominant in most cases and hybrid offspring usually resemble it more than the pollen parent. Most wild plants of "N. × kinabaluensis", for example, show a greater affinity to "N. rajah" than "N. villosa" and are thus thought to represent the cross "N. rajah" × "N. villosa". However, specimens have been found that seem to be more similar to "N. villosa", suggesting that they might be the reverse cross (see [http://www.scarnivores.com/showphotos.asp?id=N|~x~kinabuluensis]). The same is true for other hybrids involving "N. rajah".
