and often lobed at apex, petiole equaling the blade, 

 younger parts floccose; stems subscapiform, 2-4' long, 

 erect or ascending, rough, scarcely at all glutinous, little 

 enlarged above; heads large, nearly i' high, with broadly 

 linear green but rough scales; pappus oblong to oblong- 

 cuneate, about half the corolla tube, lacerate, glabrous. 

 This is my No. 1232. Watson's specimen from the Uinta 

 Mountains, Utah, is much the same. The plants are 

 perennials with very many long branches which are pros- 

 trate. This is close to C. Nevadensis. 



Ch^nactis Douglasii var. Montana. This includes 

 most of the forms usually referred to the var. alfina of 

 Gray. It includes all the forms so referred in the Na- 

 tional Herbarium, except Watson's specimen mentioned 

 above, and Patterson's, from Gray's Peak, Colorado. 

 All are perennial; peduncles not scapiform, but plants 

 much reduced in the extreme forms; pubescence less 

 floccose, otherwise much as in the type. This is the 

 usual form of the higher mountains, from 7000° to 9000° 

 alt., and ranges from the Rocky Mountains of Colorado 

 to the Sierras. 



RiDDELLIA TAGETINA var. PUMILA. 



No. 5474. June 21, 1894, Grand Junction, Colorado, 

 4400° alt., in gravel, in open places. 



Depressed from a thick, branched, woody base; stems 

 flexuous, 4-8' long; leaves all entire, obovate to oblance- 

 olate, \' or less wide and 2-3' long, villous or rarely 

 woolly ; heads never clustered, about 10" long, very villous ; 

 peduncles i\-a^' long; rays 6" long, broadly oblong; pap- 

 pus oblong, truncate to erose, \ the smooth angled, sul- 

 cate akene. 



This grows on gravelly and high banks of the Grand 

 River, in very dry situations. It was also collected by 

 Miss Eastwood in the same locality before I found it.
