§ 2. TRiCHOPHfLLUM. Larger, erect : heads when clustered small, when 

 solitary commonly rather large : involucral bracts of firm texture : rays and disk- 

 flowers golden yellow ; tube of corolla commonly glandular or hairy : anther-tips 

 ovate, mostly obtuse : akenes linear or cuneate-linear, glabrous or nearly so : 

 pappus of short opaque and firm nerveless and pointless palese, sometimes very 

 small, rarely obsolete or wanting. — Gray, Proc. Am. Acad. xix. 25. Tricho-

 patee much shorter than the akene: leaves mostly lobed or divided, and the margins revolute. 



E. stsechadif olium, Lag. 1. c. Canescent with close-pressed pannose tomentum, at length 

 partly denudate, 1 to 4 feet high from a woody base : leaves once or twice pinnately parted 

 into linear divisions and rhachis, or the upper linear with a pair of lateral lobes, or some of 

 them entire, upper face soon glabrate and green : heads 3 or 4 lines high, numerous in
