3-4 series, usually pale and chartaceous, rarely slightly herba- 

 ceous, the lower somewhat glandular; rays none; the dull bristles 

 of the pappus unequal and longer than the yellow tubular disk 

 flowers; akenes oblong, flattened, and villous with somewhat 

 appressed hairs; the style branches linear-lanceolate. 



Rocky hillsides, Eugene, Oregon. Bradshaw no. 1944 (the 

 type); no. 1885; and no. 1914 (in the U. S. National Herbarium). 

 The duplicate of the type is to be placed there also. Ciisick (as 

 E. Engelmannii), rocky hillsides, Willamette X'alley. 



This species first came to my attention three years ago, 

 when I thought it was an Aster. Since them I have come to 

 the conclusion that it belongs to the genus, Bucephalus and 

 that it is very closely related to E. Engelmanni. It seems to be 

 nearer to that species than to any of the others. The differences, 

 however, between it and that species are very evident, even 

 from a casual study. The general appearance is very similar. 

 The stems and leaves are of the same color; but the stems of 

 E. Englemannii are much more glabrous, and the leaves somewhat 

 broader. The heads of £. vialis are smaller and more narrow 

 than those of E. Engelmannii; the former never has rays, and 

 the bracts of the involucre are more narrow and pale than in 

 the latter. The bracts of the latter do not seem to be so glan- 

 dular. From my observation, £, z;*a/i5 is a plant of the lower 

 hills, while E. Engelmannii is one of the mountains. 



My first specimens were obtained on Skinner's Butte which is 

 situated between the city of Eugene and the Willamette river, 

 both being just north of Eugene. In the open woods at the 

 summit, under the Douglas firs, the species is not uncommon. 

 Some six miles south of Eugene, on the base of Spencer's Butte, 

 in similar locations, I have collected it this summer. 



This proposed species is so named, due to the fact that all my 

 collections were made from plants that were growing about paths 

 and roads either in open wooded areas or along the banks facing 

 the Willamette river. — R. V. Bradshaw.
