Thanks, Windi (^_^)

I was told the name from a friend who brought back the plant to Thailand.

Thank you for your correction. I knew sometimes "Zebra" turn to be "Tiger" via people!

Actually, I'm not agree with the name ending with "ensis" or "ense"
because it refer to the "place" of origin that the plant occurs or found.
So 'Boncel' should be right, and as you mentioned, let the owner decide to call this special treasure.
