Actually, the synonym on the webpage I cited is Nelumbo capsica. The
question was about N. nucifera caspicum.

Yes, since Nelumbo nucifera caspicum is not an accepted form of reference
for any name it can be taken to mean anything.

Actually there is a little more to it than that ...

If the species Nelumbo caspica ever is treated as a cultivar it will
automatically be Nelumbo nucifera 'Caspica' (ICNCP 17.3)

If any infraspecific combination based on Nelumbo caspica is made (don't
seem to be ?) then it is recommended to retain the epithet "caspica"
