Involucral scales linear, obtuse. Receptacle pitted. Flowers purplish at 

 apex, the female flowers equalling the disk. Achenes ovate-compressed, 

 margined, hairy. Pappus rufescent.

14. ERIGERON MYOSOTIS Pers. 



Stem simple, 30 cm. high, about \-headed. Leaves linear, hirsute. 

 Flowers purplish. 



J. D. Hooker unites this with E. alpinus L. Against this A. Franchet 

 says, "It differs by having its leaves narrower, linear or linear-spatulate, 

 always very close on the stem, and the inflorescence is in a long raceme, 

 though sometimes reduced to a head. Peduncles very short or long, but 

 always parallel with the stem. Leaves less diverse than in E. alpinus, 

 and not rosulate at the base. Flowers purplish."
