An annual of calcareous grasslands in karstic areas, on maritime dunes and montane limestone cliffs. 0-550 m (Ben Bulben, Co. Sligo).
The distribution of this tetraploid species appears to be stable. Plants from cliffs on Ben Bulben approach the boreal species E. lapponica, but may alternatively be derived through introgression with E. frigida. Hybrids between E. salisburgensis and other Euphrasia spp. are rare, and are largely but not completely sterile. A specimen from Yorkshire collected in 1885/6 is now considered to have resulted from confusion or mislabelling in the herbarium.
European Boreo-arctic Montane element; Irish material is referable to the endemic var. hibernica.
