P. nepalensis I hope is a much smaller delicate plant with much smaller infl and distinctly winged petiole. This plant has has the habit of P. chinensis. One should always look for some matured flowers in which perianth becomes larger fleshy and blue-black in fruit. And yes the two P. auriculata (now treated as synonym as mentioned by Dines ji) and P. chinensis are very distinct and not synonyms.
