Calyx lobes:
As I understand it, a key feature that separates
Pinguicula macroceras subsp. macroceras from
Pinguicula macroceras subsp. nortensis is how deeply divided the calyx lobes are.
The calyx lobes of this plant are clearly deeply divided, so by this metric these plants would be classified
as Pinguicula macroceras subsp. macroceras, but I'm not sure. I expect some experts will contact me
and chide me shortly. I'm looking up Casper's 1962 paper as soon as I can!
