Sheldon: SPECIES OF astragalus. 145 



slightly arcuate, unilocular, but with ventral suture somewhat 

 intruded, lined within with cobwebby hairs which traverse the 

 cavity, few to many seeded. 



Collected at Klikitat Prairie, Washington, June, 1880, by 

 Thomas J. Howell; also at Reno, Nevada. Communicated by 

 Miss Alice Eastwood. The species is near to Astra f/alus 

 piirshii DouGL., but the narrow leaves and peculiar pods char- 

 acterize it. These latter resemble very closely the galls pro- 

 duced on leaves of Quercus by Andricus lanae Fitch.

The difficulty which many botanists seem to have had in 

 determining the limits of Astragalus injlexus Dougl. and 

 Astragalus ijurshii DouGL, has probably arisen from the non- 

 consideration of this species which is intermediate between 

 the two.
