OK let me guess,
Nepenthes 'Accentual Koto' [ = Nepenthes x (thorelli x (ampullaria x rafflesiana)) ]
Nepenthes 'Arakawae' [ = Nepenthes x (alata x (maxima x northiana)) ]
Nepenthes X chelsonii [ = Nepenthes X ((ampullaria x rafflesiana) x (hirsuta x rafflesiana)) ]
Nepenthes ‘Yatomi’ [ = Nepenthes X (thorelli x veitchii) ]
Please correct me if i'm wrong
