About Euphrasia salisburgensis Funck ex Hoppe
Euphrasia salisburgensis Funck ex Hoppe has a pan-European distribution, and grows widely across base-rich sub-alpine areas. The variety hibernica Pugsley has been recorded in Ireland since the late nineteenth century, growing on limestone rocks and sand dunes there. This variety differs from other Irish members of the Euphrasia genus by having a glabrous capsule, usually red-brown or bronze-colored foliage, and non-contiguous leaf teeth. The subspecies E. salisburgensis subsp. schoenicola is endemic to Gotland. Like other species in the Euphrasia genus, E. salisburgensis is a hemiparasite. In their flora of the Burren, Webb & Scannell found that E. salisburgensis is closely associated with Thymus praecox, and suggest it may be a specific hemiparasite of this species. The subspecies E. salisburgensis subsp. schoenicola is instead thought to be a specific hemiparasite of the sedge Schoenus ferrugineus.
