Nepenthes hybrids and cultivars reduced to lowest terms

Published online (2022)

If you have hybrid or cultivar names to add, feel free to let me know.
Main sources: Carnivorous Plant Database; International Carnivorous Plant Society; Carnivorous Plant Photo Finder; Leilani's Grex List. Plus various nurseries.
For the aka parts I mostly used Fukatsu.
When searching for a name, add a colon: "hookeriana:".
I skipped the "? x ?" and "parent x ?". Grex names are listed as cultivars.
Use the Carnivorous Plant Database: to check the legitimacy of a name; if a name appears in black more than once; if you see a question mark.
All with a pinch of salt, because many hybrids have a dubious parentage.
Don't be fooled by the number in parentheses, it's just for the record and only broadly indicative of the influence of the species. For example, ampullaria(5) x gracilis can mean 1) that ampullaria was crossed four times with ampullaria and then once with gracilis, which would make the plant 50% ampullaria and 50% gracilis, or 2) that ampullaria was crossed once with gracilis and then four times with ampullaria, which would make the plant mostly ampullaria.
The epithets alata and thorelii are between double quotes because there are doubts about those two names today, let alone fifty or a hundred years ago, when the hybrid was made.
Needless to say, the Indochinese species are treated according to this page.
Some problematic names are not in the main list.
See the notes at the bottom of the page for more comments.
