family, who have long resided there. The special habitat of the 

 species, the wooded crowns of several high hills along the Missouri 

 River at this place. The fertile and sterile plants were growing 

 together, the males by the hundred, the fertile plants rather scarce, 

 therein differing from, all the other broad-leaved species of this 

 region, the sterile plants of which have never been seen. 



This plant is distinct from all the broad-leaved species known 

 to me to occur in this region, as shown by the following key: 

 Scales of the fertile involucre broad, with broad showy tips. 



Pappus-tips in male narrow, serrate 4. occidentalis. 



Pappus-tips in male wide, crenate A. calophylla. 



Scales of the outer involucre narrow 



vScales not showily scarious-Lipped. 



Scales few, subequal; pappus-tips in male 



subserrate A. umhellata. 



Scales many, well-imbricated; pappus-tips in 



male crenate A. mesochora. 



vScales showily scarious-tipped, numerous, un- 

 equal, in several series ; pappus-tips in male 

 narrow, serrate A. ampla. . .

The writer while comparing specimens of Hemerocallis fulva 

 and flava during the past summer, was led to note peculiarities 

 of these two species, which do not seem to be generally known 

 to botanists. It will be convenient to introduce excerpts from 

 our common manuals.
