Specialty Gardening: Which Jasmine is it? Star or Royal or both?, 1 by JBerger

I purchased two jasminun a year or more ago.
The first one was from Logee's and it was Jasminum Nitidum, 'Royal Jasmine"
The Second was from TopTropicals and it was Jasminum Nitidum " Star Jasmine"

Both are identical plants and both have identical pink buds. The Star is in bloom now
and this is it.
The Royal buds have not opened yet but I know they will be identical.

How can I find out which it is, or is it called both? I have looked on DG and written to several people who have it . Still not clear.
Any suggestions?
