Notes: Euphrasia hudsoniana is distributed from Labrador west to Lake Winnipeg (Sell and Yeo 1970) and with arctic occurrences in northern Labrador (Nain), Ungava, and along Hudson Bay. It is characterized by having conspicuously longer hairs on leaves and calyx than the majority of northern Euphrasias but only with eglandular hairs, with first flowers at comparatively low nodes (4.-6. node), leaves more or less sharply dentate, flowers comparatively large and white-lilac, calyx with blackish spots (as in E. wettsteinii), and the capsule more or less equalling the calyx in length.
