Paphiopedilum ×petchleungianum O. Gruss (Orchidee (Hamburg) 52: 611. 2001), a natural hybrid between this taxon and P. dianthum, was described from Wenshan of SE Yunnan. Its flower is similar to that of this taxon, but its petals are narrower and longer and its staminode very similar to that of P. dianthum.
