Complex Nepenthes hybrids with valid names
Main page: Nepenthes hybrids and cultivars reduced to lowest terms
On the main page, I talked about some stats I did, based on the CPD alone: there are 186 hybrids, which have been given 455 different names. Of these 455 names, 234 are latin names and 221 are cultivar names. There are 37 latin names that can boast to be the first validly published for the hybrid. Of these 37 names, 22 belong to simple hybrids (two parents) and 15 belong to complex hybrids (more than two parents). I thought those 15 were worth some extra attention, so here they are.Related articles:

The name appeared as N. dormaniana in 1880. That should be from Charles Dorman, a British orchid expert who also named Cattleya dormaniana after his son Arthur Dorman. Later on, the name appeared as N. dormanniana, and I can't find a reason for that.
