description
The summer rosette of Pinguicula gypsicola has linear-lanceolate, finely ciliate leaves, 4 to 7, occasionally up to 13 centimeters long. Towards winter it forms a winter rosette with a diameter of only two to four centimeters, which consists of numerous, tiny, almost scale-like leaves. A long-spurred, large, violet-purple flower , which resembles that of a violet, stands on a flower stem that grows up to 17 centimeters high . Pinguicula gypsicola blooms equally from winter and summer rosettes.
The number of chromosomes is 2n = 22.
distribution
Pinguicula gypsicola is a lithophyte that is native to wet, pure gypsum rock in Mexico . The plant is only known from two, about fifty kilometers apart locations in the state of San Luis Potosí . It prefers shady locations that fall completely dry in winter and are exposed to temperatures below 0 ° C and occurs in association with other xerophytes such as Cactaceae , Agave stricta , Selaginella cuspidata , Agave striata , Dasylirion longissimum , Dodonea viscosa and Hechtia glomerata .
