Notes:

• Cribb (1998) considered it to be a natural hybrid between P. hirsutissimum var. esquirolei and P. barbigerum.  He cites personal communication with Cox, who did a molecular analysis on a cultivated plant and concluded it was probably of hybrid origin.
• Averyanov (2003) considered it to be a, "more or less stabilized natural hybrid of P. hirsutissimum and another slipper species of P. insigne complex, most probably Paphiopedilum helenae.  The morphology of P. x herrmannii is obviously intermediate between its putative parents, leaving little doubt as to its origin."  Averyanov cites discoveries of P. x herrmannii growing in between P. hirsutissimum var. esquirolei and P. helenae as evidence for this origin.
• Braem (2003) considers it a "stabilised natural hybrid" and thus a valid species.
