No. 8106, collected July 14, on the banks of Deer creek 

 near Nevada City, Nevada county. Thi.s was a shrub consider- 

 ably larger than no. 8087, and the leaves mostly larger. These 

 specimens more nearly approach C. californica in habit and ap- 

 pearance, but the leaves lack the peculiar yellowish cast present 

 in typical plants of that species. The glabrous red bark of the 

 young branches is another distingnishing character. In cali- 

 fornica they are dull brown, pubescent.

No. 7895, collected May 29, at the River bridge near Red- 

 ding, Shasta county, growing in sand and gravel under trees. 

 Some of the leaves are four inches long and an inch and a quar- 

 ter wide, shortly acuminate. As it grew here it was a slender 

 spreading shrub perhaps six feet high, growing in clumps. The 

 type, collected in "montibus Sacramento," probably along the 

 Vuba river, had "foliis perennantibus oblongis acuminatis i ^- 

 2^^ poll, longa, 6-9 lin. lata." 



No. 8104, collected July 14, near Grass Valley, Nevada 

 county, is more nearly typical in that it has narrower leaves, 

 which are also thicker than those of no. 7895. It grew in more 

 exposed situations, and is from the type region. 



No. 7859, collected May 26, on dry hills about two miles 

 west of Redding, Shasta county, has rather small leaves, more 

 like those of the type in size, but the most of them merely acut- 

 ish. The shrubs were growing on a stony ridge with a south- 

 erly exposure.
