Origin of depicted specimens: Spain, Prov. de Albacete, between Alcaraz and Orcera, Nascimiente del Rio Mundo/Cueva de los Chorros, 950-1100 m, limestone, collected by myself April 15, 1995. See 950313. This 'species' is something in between P. longifolia and P. vallisneriifolia. Geographically and climatically the evolution of sort of a transition stage between both species could be plausible. The leaves are more longifolia-like whereas the corolla, particularly the calyx and spur, tend more towards P. vallisneriifolia.
