Pinguicula in Japan

[sweetpea]

There are no new photos. They are very old photos. Please be patient. After posting the photos, I will post my question.

First of all,
Pinguicula ramosa,

[sweetpea]

Pinguicula macroceras Lowland form

[sweetpea]

Pinguicula macroceras Highland form

[sweetpea]

Please see the Lowland form and Highland form of Pinguicula macroceras in the photos I posted. For over 40 years, I've been feeling a bit uncomfortable with these being called the same botanical name such as Pinguicula macroceras, but I don't know the terminology that points out what is taxonomically different. These two Pinguicula macroceras are conveniently called Highland form and Lowland form by hobbyists. The impression I get from the appearance of the Lowland form is similar to that of Pinguicula macroseras ssp. nortensis, but the way the flowers of the Highland form open is similar to that of Pinguicula vulgaris.
I'm ignorant of information, so the difference between the two may have been published in the literature.

I'm not a taxonomist, therefore I have no intention of discussing anything here.
I just hope someone gives me a fair and reasonable answer.
Or
I think some members of this forum have experience growing them side by side. Please let me know your impressions.

Kind regards from the Far East
