Rosa CAUFORNICA Cham. Linnaea ti: 35. 1S27. 



No, 8582, collected May 28, about tw(; miles bcxoivl San 

 Mateo, San Mateo county, on the Half Moon Bay road, .L,rn>\vin*( 

 on moist banks near shrubs and trees. The type was obtained 

 near San Francisco. Our specimens agree with the ori<j;inal de- 

 scription, except that the leaves are glabrous above instead of 

 p'.ibescent.

 Amelanchier GRACILIS Heller, Muhlenbergia, 1: 59. 1905. 



No. 8531, collected May 10, near the summit of the grade 

 between Smith Creek and Hall's valley, Santa Clara county, ele- 

 vation 2300 feet. Here it is a shrub eight or ten feet high, the 

 numerous stems forming a symmetrical mass, the whole covered 

 at the time with many flowers. It differs in other respects from 

 the type in having the fewer teeth at the ape.x of the leaf cre- 

 nate rather than serrate, and the outside of the calyx smoother. 

 It may be distinct, but I do not at present feel warranted in de- 

 scribing it. One thing is certain, liowever, and that is that we 

 do not have A. abiifolia in California.

No. 8534, collected May 10, at Smith Creek, Santa Clara 

 county, elevation 2100 feet, on wooded stream banks, rather fre- 

 quent. A good sized shrub with small oval, short pointed leaves 

 obliquely narrowed at base, the margins closely serrate with 

 short, appressed, awn-tipped teeth, perfectly glabrous beneath, 

 in which it differs from the original collected on "plains of the 

 Oregon toward the sea, and at the mouth of the Wahlamet." 

 The leaves of the type are "sharply serrate with straight teeth, 

 often emarginate at the base, more or less pubescent beneath," 

 the drupe red. In ours the drupe is said to be "red or dark 

 purple'' h\ both Greene and Jepson.
