being of an extremely delicate and almost fibreless tissue, the 

 leaves when dry being as translucent as a delicate green sea-

 foot high, sparingly strigulose under a lens, leafy to above the 

 middle, racemose-panicled at summit : leaves rather crowded, 

 oblong-linear, entire acute, green and glabrous except as to the

Salt marshes about Beck's Hot Springs, Utah, at 4,500 ft.,

Aster leucopsis. Rather slender, rigid, 1 to 2 feet high, 

 decumbent at base, racemose to subpaniculate from the middle ; 

 plant whitish with bloom, very sparsely scabrous, the margins 

 of the lance-linear entire leaves strongly serrulate-scabrous : 

 pedicels of the many middle-sized heads with many spreading 

 linear bracts ; involucre turbinate, closely imbricated, the 

 green tips of the scales conspicuous on a ground of white : 

 rays not large, pale violet. 



Along irrigating ditches in the vicinity of Salt I^ake City,

Brigeron minusculus. lyow cespitose perennial with muti- 

 cipitous short caudex surmounting a stout tap root ; flowering
