Paphiopedilum Clifton Booth or ??

[shadytrake]

Okay, I got these Paphs from a going out of business sale and they have tags Paphiopedilum St. Swithin x primulinum.

I was researching the name information so I can enter it into my Journal and also so I can make sure the extra one is labeled correctly before I send it to its new home and I am puzzled.

I find that the cross is showing registered as Clifton Booth BUT the other way around. Paph primulinum (seed parent) x Saint Swithin (pollen parent).

So is it more likely that my tags are printed wrong (not handwritten BTW - printed) or do you think I have a different unregistered cross?

OR - am I having a totally dumb moment and am just reading it all wrong (seed parent vs pollen parent).

Here is a link showing it labeled the way my tag reads.

RHS shows it the other way around.
