 below the terminal panicle, 2 to 4 ft. high; herbage grayish with a 

 minute rough pubescence; leaves oblong, acute at apex and tapering 

 below into a short petiole, the lower varying to oblong-obovate and 

 serrate, the upper smaller, narrow and entire; panicle usually com- 

 pact, dense, not leafy, 4 to 13 in. long, made up of raceme-like clus- 

 ters (or when elongated, secund), seldom recurved at tip, sometimes 

 spreading in age; heads 2J to 3J lines long; bracts of the involucre 

 oblong-linear or lanceolate, somewhat pubescent; rays 7 to 12, pale 

 yellow, about as many as the disk-flowers; achenes pubescent.

 base, or entire; panicle dense, thyrse-like, the heads little if at all 

 secund in the raceme-like clusters; heads small, 2 lines high or less; 

 bracts of the involucre thin, linear; rays 10 to 16, narrow, usually

 spatulate, rounded at apex, narrowed to a long marginal petiole, more 

 or less serrate above the middle; heads 4 lines high, almost or quite 

 as broad, the clusters aggregated in a single spike-like thyrsus ter- 

 minating the simple stems; bracts of the involucre linear-oblong to 

 oblong; rays about 7 or 8, inconspicuous, shorter than the disk; disk-
