places below the laTce. Later it was found at 10500 feet in 

 gravel on the crest of the main ridge, the plants here lower and 

 more tufted. It is a beautiful plant, with bright violet-purple 

 small flowers, the short and broad calyx lobes prominently 

 hyaline. 



Arnica chionophila Greene, was collected "near the summits 

 of the Ruby Mountains, Nevada, in the vicinity of perpetual 

 snow, 20 July, i8y6," by Dr. Greene. The more exact locality 

 is on the Clover mountains back of Deeth. I have specimens 

 gathered at 9000 feet which arc doubtfully referred here. They 

 have two pairs of stem leaves, the upper reduced and usually 

 acute or acuminate, the other on long, more or less winged peti- 

 oles, either cuneate or somewhat cordate at base, while the basal 

 leaves are semi-cordate. All of the leaves are entire. Not only 

 the peduncles "under the involucre," but the whole stem is "vis- 

 cidly glandular and villous." The short scattered hairs on the 

 leaves can hardly be called "thinly tomentulose," but there are 

 "small sessile resinous glands on both faces." The involucral 

 bracts are thinly villous rather than "puberulent." While not 

 agreeing very well with A. chionophila, it can hardly be referred 

 to A. cordifolia.
