No. 7904, collected May 30, in a meadow about two miles 

 northeast of Redding, Shasta county. It was not very plentiful, 

 nor was it noticed elsewhere in the vicinity. Douglas obtained 

 the type somewhere in the coast region, probably about Mon- 

 terey, where it is not uncommon.

 No. 8055, collected June 17, in sandy soil between Sisson 

 and Barnard station, Siskiyou county. It was not plentiful 

 there, and is evidently rare, there being only one specimen of it 

 in the herbarium of the California Academy, collected at Janes- 

 ville, Lassen county, by T. S. Brandegee, June 28, 1892.

No 7940, collected June i, near Shasta Retreat, Siskiyou 

 county, in rather rich sandy soil near trees. These specimens 

 have longer and narrower leaflets and longer and more naked 

 stems than the typical form, but it is a species somewhat vari- 

 able as to foliage and growth. The type came from "wet ra- 

 vines, Dufheld's Ranch [near Auburn, Nevada county]. Sierra 

 Nevada; May 10; and hill-sides. Mammoth Grove, California; 

 May 15." It is plentiful about Donner Lake, on the east side 

 of the Sierra, elevation 6000 feet.
