2 mm. wide at base, 3 mm. at apex, convex dorsally and rough- 

 ened with transverse ridges, the two cells closely pressed against 

 each other, appearing as if only one, but readily separating. 



The type is no. 8156, collected April 11, 1906, on grassy 

 hills near Pollasky, Fresno county, California. It is rather com- 

 mon in the vicinity having been noticed two or three miles 

 above on the other side of the San Joaquin river in Madera 

 county. It was at once recognized as different from any of the 

 forms of H. didymocarpiis hitherto observed by the short com- 

 pact fruiting heads, and the densely white-pubescent pods much 

 exserted from the calyx. Although the flowering calyx meas- 

 ures only a little less in length than the pod, the breadth of the 

 pod distends it and causes it to appear very short.

 Nuttall perhaps collected the type near Monterey, where Hart- 

 weg collected P. cucuUata^ but the exact .station is not given.
