being of an extremely delicate and almost fibreless tissue, the 

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

 weed. It is, of course, a plant widely separated from the 

 other geoKi*aphically and ecologically. 



New Western Asteraceae. 



Aster hai^ophilus. Stems slender, decumbent, /4 to 1 

 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 

 serrulate-scabrous margin, all one-nerved, deflexed : heads 

 middle-sized ; involucre turbinate, much imbricated, with 

 scales glabrous and glandless : rays pale violet. 



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

 6 Sept., 1906, A. O. Garrett. In foliage and habit as well as 

 size reminding one of A. caiupestris^ but not closely related to 

 that, the involucre being in every way different, and more like 

 that of A. adsceiidens. 



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 Lake City, 

 Utah, very common. Here described from specimens by A. O. 

 Garrett, 5 Sept., 1905. 



Erigeron minuscui^us. Low cespitose perennial with muti- 

 cipitous short caudex surmounting a stout tap root ; flowering 

 branches slender and wiry, only 2 or 3 inches high, monoce-
