occurs in favorable situations at other places in the vicinity, as 

 near the south shore of Donner La'ke at 6000 feet. It has here- 

 tofore been referred to the eastern V. septentrionalis Rydb. (K 

 sylvatica Banks), which occurs with certainty only as far west 

 as the eastern borders of Idaho. 



AcMllea arenicola 



Stem stout, 4dm. high, 5mm. in diameter near the base, 

 simple, clothed throughout with a close dense covering of per- 

 sistent woolly hairs, leafy throughout: basal leaves about 8cm. 

 long, those of the middle and upper part of the stem crowded, 

 gradually reduced in size, the uppermost about 2cm, long, all 

 linear in outline, the largest about icm, wide, pinnatifid with 

 rather fine, crowded aristate-pointed segments, especially those 

 of the middle and upper parts, where the divisions are concealed 

 by the thick wool: corymb very compound, rounded rather than 

 flat topped: heads 5 or 6mm. high, woolly as the other parts of 

 the plant: involucral bracts with prominent yellow keel which 

 is bordered with green, margins thin, brown, often somewhat 

 lacerate: rays small, less than 3mm. across: immature achenes 

 linear, slightly margined. 



No. 5608, collected May 27, 1902, on sand hills at the up- 

 per end of Bodega Bay, Sonoma county. Probably nearest to 

 A. Californica Pollard, but differing in several particulars, and 

 remarkable for its excessive woolliness which seems to be per- 

 manent, although a little less dense at the base than on the up- 

 per parts of the plant.
