short straight hairs, broadly club-shaped, gradually enlarged 

 from 2 mm. at the base to 6 or 7 mm. near the top, the folds at 

 the" top edged for a depth of 2 mm. with bright yellow, the mid- 

 dle fold 2 mm. broad, with a slight concavity, the lateral ones 

 narrower, each raised into a narrow ridge; the minute white 

 slender teeth less than i mm. long; the pale purple galea erect, 

 extending 2 or 3 mm, above the other parts, densely bearded. 



The type is no. 7677, collected April 13, 1905, at Kramer, 

 San Bernardino county, California, in the Mojave desert in sand. 

 It was first noticed from the train some distance east of Mojave, 

 its peculiar dark purple aspect at once marking it as something 

 new. A single plant was found on the desert just north of 

 Randsburg, and it had been brought in from a mining camp 

 nine miles north of Randsburg, showing that it is not uncom- 

 mon in the western part of the Mojave desert. It is one of our 

 handsomest species, related to O. purpurascens.
