|discussion=<p><i>Euphrasia hudsoniana</i> has been reported from Alberta; the voucher specimen supporting that occurrence has not been verified by the author.</p><!--
--><p>The status of var. contracta P. D. Sell & Yeo and var. ramosior P. D. Sell & Yeo is unclear. Some specimens identified as var. contracta represent precocious states of var. hudsoniana. Variety ramosior specimens look very different from typical var. hudsoniana, resembling the hybrid <i>Euphrasia nemorosa</i> x <i>E. hudsoniana</i>. But variation in their characters is consistent, particularly their minute corollas and type of pubescence, which is not typical of <i>Euphrasia</i> hybrids.</p>
