 5 ram. long, i mm. wide at base, caducous: upper calyx lip 

 ovate when spread out, 4 mm. long and as wide at base, 2-tooth-

 a narrow groove, the apex on the dorsal side with a sort of keel, 

 the whole broadly obovate, i cm. wide; wings inflated to about 

 5 mm., and 5 mm. deep, the upper edges almost meeting, a chan-

The type, in the herbarium of the Nevada Agricultural Ex- 

 periment Station, is Heller 10080, collected on grassy hills at 

 the Dalles, Wasco county, Oregon, May 23, 1910. 



This species is related to L. nevadensis Heller, Muhlenber- 

 gia 6: 107, but has smaller flowers of a different shape though 

 of the same type, rounded in outline, the banner and wings close 

 together, the face of the banner turning brown in drying. It 

 would be classed among the Saxosi according to ])ubescence in 

 Piper's Flora of Washington.
