 lip concave, 2 mm. across, entire and rounded at the apex; lower 

 lip in the natural state appearing narrow, only 3 mm. wide by 

 the turning down of the edges, but when spread out obovate-

The type, in my herbarium, is no. 8574, collected May 28, 

 1907, on the slope above Crystal Springs, San Mateo county, 

 California, on the Half Moon Bay road, elevation 450 feet, in a 

 field in damp grassy places. It is remarkably distinct from any 

 of the known coast forms, and was at once recognized as unde- 

 scribed, differing in its slender erect habit, green appearance, 

 comparatively narrow leaves and narrow flowers.
