 Washington, June 13, 1898, on grassy slopes. The type speci- 

 men is in my private herbarium.

 which is usually found in places where there had been considerable 

 moisture in early spring, while later in the season, the ground be- 

 comes dry and baked. The flowers of Q. Quaviash are less deli- 

 cate^ and are of a rich blue-purple color.

 I mm. wide, the rachis and leaflets sparingly pubescent : flowers 

 not seen: styles plumose, 2-3 cm. long, . recurved, the plumes
