Origin of depicted specimens: Switzerland, canton Bern, Grimsel-Pass, 1800 m, granite (site of the holotypus), collected by myself August 16, 1968. 9501 shows the region of the typus site in summer. At left Grimsel-Pass (highest point at the little lake, 2165 m). P. leptoceras grows on both sides below the pass. On the Pinguicula-sites the snows lasts for 8-9 months each year.
The latin name leptoceras is misleading: Usually the spur isn't slender at all. See also pictures 70132 (with P. grandiflora and other sp.) and 70146 (with P. longifolia and other sp.).
