ORIGIN AND
HISTORY :
Although
it has been identified with P. oblongiloba (S. Zamudio), Hans Luhrs wrote
that it differs from the latter by having much shorter, narrower, and deeply
involute summer leaves, and by forming gemma-like bulbs, putting forth long
whip-like runners, budding at the end of iyts tips, a feature which is unique in
the Mexican Pinguiculas and is known in P. vallisneriifolia for
exemple.

It
was in culture at a unique sample in Europe but lost. Up to now, the plant
could only live in Japan but I have no confirmation.
