rymbs ; involucre hemispherical ; the outer scales rather loosely appressed, 

 herbaceous, smooth, linear-spatulate, acute ; inner ones lanceolate, with char- 

 taceous margins ; rays white. — It is apparently intermediate between A. mul- 

 tiOorus or A. falcatus and A. simplex, and its place cannot be fixed satisfacto- 

 rily before a general revision is made of North American Asters. Truckee

Aster Douglasii, Lindl. Stems erect, about 4° high, nearly or quite 

 smooth, paniculately branching above ; leaves thin, smooth, serrated or en-

 often ample, 6-9' long, 1-2' wide ; lower stem-leaves lanceolate or linear- 

 lanceolate, sessile or short-stalked ; uppermost ones linear, all of them acute ; 

 heads large, peduncled, single or 3-5 together at the ends of the branches ; 

 scales of the hemispherical involucre rather large, loosely imbricated in about 

 3 rows, smooth, broadly linear or the outer ones spatulate, the base charta- 

 ceous, the tips green, slightly spreading ; rays large. — Oregon and Califor- 

 nia. Valleys and canons from the West Humboldt Mountains to the Wah-

 heads solitary, rather large ; scales of the hemispherical involucre imbricated 

 in about 4 rows, linear-acuminate, about 4" long, glandular-puberulent, all
