Confidence: I'm as sure as I can be.
Notes: Very typical material.
If a Euphrasia is not recorded to species, it is better recorded as "Euphrasia sp.", not "Euphrasia officinalis agg.", as true E. officinalis and its close allies are diploids - while this is one of the many quite separate tetraploid spp.
