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.

Map / LOCALISATION : 

 

From Mexico, State of Oaxaca, ca. 3 km se. of Ixtlan de Juarez, on steep banks in pine and oak woods, ca. 2300 2400 m., State of Oaxaca, Distr. Ixtlan, Sierra de Juares, ne. of C. Pelon, on steep loamy bank, +/- 2700m.; in umbrosis Totontepeque.

HABITAT:  

As stated before, on steep banks in pine and oak woods, at altitudes of 2300 2400 m. or on steep loamy bank, +/- 2700m.

Introduction in culture :

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.
