I gathered this Euphrasia in 1891, and, being new to me, I 

 provisionally named it, but for various reasons it has until lately 

 remained neglected in my herbarium. I now take the opportunity 

 of recording and describing it, as I still think it distinct ; and 

 I believe Prof. Wettstein inclines to the same opinion, though he 

 may reserve his final judgment. 



I only know Euphrasia americana Wetts. from Prof. Wettstein's 

 description and figure in his monograph of the genus. It is de- 

 scribed as a slender plant branching from the middle and above it, 

 its bracts with a cuneate base, without glandular hairs, and the 

 lower teeth aristate ; the flower-spikes neither dense nor elongated.
