Closer view:
Students of Pinguicula will tell you that the shapes of the flower petals are
one of the features that separate these eastern Oregon Pinguicula macroceras subsp. macroceras plants from
Pinguicula vulgaris. Furthermore,
these plants are supposedly sufficiently different from the coastal Oregon-California plants so that
the latter are called Pinguicula macroceras subsp. nortensis. My own opinion on the separation
of the species into these subspecies is still a little uncertain. I need to see both plants, and also
Pinguicula vulgaris, at more sites before I will feel comfortable making an assessment.
Here is another photograph of these flowers.
