volucre 1012, linear and acuminate, about i cm. long, grayish 

 pubescent, a very few calyculate ones at base: achenes striate, 

 fusiform but tapering more upward than downward, about 7 mm. 

 long, and the bright white pappus the same length. 



Seemingly somewhat related to Crepis gracilis (D C. Eaton) 

 Rydb., but smaller. Collected at Sulphur Springs, Grand 

 county, Colorado, June 28, 1905, no. 2979. 



< Ag^oseris leptocarpa 



Perennial, one to four stems i-i.5dm. high from the root, 

 slightly woolly pubescent at the base of the bracts: leaves linear, 

 from entire to runcinate pinnatifid, 5-8 cm. long, 3-5 mm. wide, 

 the lobes 3-5 mm. long, glabrous and a little glaucous or some- 

 times slightly villous-pubescent: heads about 2 cm. high, the 

 bracts in three series, the outer about 7 mm. long, slightly pu- 

 bescent, the inner 15 mm. long, glabrous: achenes fusiform, 

 5 mm. long, striate, tapering into a beak 5 mm. long, the bright 

 white pappus 8-9 mm. long. 



Related to Agoseris gracilis^ but distinguished from it by 

 the smaller size and the smaller achenes. No other of our 

 Rocky mountain species, so far as I know, have achenes so 

 small. Collected near Coulter Post Office, in Middle Park, Col- 

 orado, June 29, 1905, no. 2972.
