pus, which is also usually wavy below the summit, and which 

 also is not deciduous from the mature achene, as it is in S. 

 ligidifoluis, 



Senecio aulETicus. IvOw tufted perennial with nearly -^ A 

 naked and mostly monocephalous stems 3-9 inches high, the 

 stems and their bracts, as also the involucres floccose-tomen- 

 tulose, the foliage hardly so : blades of basal leaves suborbicu- ^/$f 

 lar to obovate, from less than /^ to 1 inch long, lightly and ^ 

 often obscurely crenate or dentate, slightly succulent, on 

 petioles of twice or thrice their length ; cauline leaves mere 

 sessile flocculent bracts: involucre campanulate, nearly V^ inch 

 high and as broad; rays deep golden yellow, elongated-oval, 

 at least 5-nerved, at apex very obtuse and with three short and 

 obscure teeth. 



The type specimens of this very good new Se?2ecio are from

June, 1904. They are in U. S. Herb., under the collector's

 the same, and are from the same general region. 



Pyrrocoma Balsamitae. Stems few, stout, 1 to 2 feet 

 high, spicate above the middle with few and rather remote 

 middle-sized heads, the whole i:)lant to the naked eye glabrous, 

 of a light-green inclining to yellowish : leaves subcoriaceous, 

 the basal 2 to 4 inches long, the oblong-elliptic blade little 

 surpassing the narrow petiole, evenl}^ crenulate or subserrate- 

 crenulate, the lower cauline spatulate-lanceolate, the upper 

 oblong, all the cauline sessile : heads broadly turbinate, 

 inch high, nearly or quite sessile, elegantly imbricated bracts 

 of involucre with linear base and rhomboid green tips, their 

 whole margin very definitely villous-ciliate : rays not numer- 

 ous, light-yellow.
