No. 7660, collected April 12, on the ridge to the right of 

 the mouth of Kern canyon. These plants are low and slender, 

 and were found sparingly on steep gravelly slopes, the elevation 

 perhaps 1500 feet. The species has apparently not heretofore 

 been reported from the foothills of the southern Sierra. 



No. 7761, collected April 24, at the foot of the mountain 

 about three miles southwest of Mojave, Kern county, on the 

 Mojave desert. The plants were prostrate, growing in rounded 

 mats in gravelly ground. The habitat is a rather unexpected 

 one. A form similar to this occurrs in the foothills of the Santa 

 Cruz mountains about Los Gatos, Santa Clara county.

 No, 8094, collected June 22, in moist meadows near Igerna^ 

 Siskiyou county, where it was plentiful. The flowers are pur- 

 ple throughout, not "white; the carina and alae tipped with a 

 fine purple." The leaves also are elliptical or oblanceolate 

 rather than oblong. The type was from "in the vallies between 

 Spokan and Kettle Falls," Washington. 



No. 8102, collected July 14, near Nevada City, Nevada 

 county, along the electric railroad growing in wet places. This 

 is a stouter plant than 8094, is a duller green, with leaflets ob- 

 tuse or merely acutish, the mucronate point absent or very short* 

 It may be distinct.
