Geography: European: NOR RUS?
Notes: Euphrasia stricta reaches the Arctic in Vardø in Norway, perhaps also in Kanin-Pechora in northeastern European Russia. Inspected material from arctic and near-arctic sites in Scandinavia belongs to var. or subsp. tenuis.
Euphrasia stricta is a common species in northern and central Europe and is characterized by flowers large and white-lilac, first flowering from low to high nodes (3.-14. node), leaves (and especially bracts) usually sharp-dentate, and with a mixture of eglandular and very short-stalked glandular hairs (but glandular hairs often absent in autumnal, subglabrous forms). Yeo assigned the northern or seasonal (aestival) race to the Atlantic E. arctica as a subsp. tenuis. It has later been considered by Nordic authors (e.g., J. Jalas and T. Karlsson) as a var. tenuis of the more generally distributed mainland European E. stricta. The type race, var. stricta, is more southern and probably non-arctic. Gusarova considers species rank for "tenuis" but then with another species name (due to homonymy with E. tenuis Wettst. from Chile).
