An annual occurring in short grasslands, on heaths, downs and dunes, in open scrub, woodland rides and upland moorlands. It is absent from agriculturally improved land. 0-825 m (Cross Fell, Cumberland).
This tetraploid species has not shown any marked change in its range since it was mapped by Perring & Sell (1968). It is the most common and ecologically diverse of our eyebrights, becoming more restricted to calcareous soils at low altitudes in the north. However, it forms hybrids with many other Euphrasia species, and introgressed populations can be locally abundant, making identification difficult.
European Temperate element.
