Daisy Fleabane Erigeron annuus (L.) 

 Pers. A rather slender, erect, leafy biennial, 

 20-150 cm. high, beset with spreading hairs, 

 lower leaves ovate, mostly obtuse, coarsely 

 toothed, upper narrower, sharply toothed, mar- 

 ginal flowers very numerous, white or tinged 

 with purple. Study well and com-pare with 

 Erigeron ramosus. The achenes are so nearly 

 like those of E. rarnosus that it did not seem 

 worth while to make drawings of the species. 



A native weed; especially abundant in thin 

 grass land.

Daisy Fleabane. Erigeron ramosus (Walt.) 

 B. S. P. Slender, erect, biennial, pubescence 

 closely appressed, 60-150 cm. high; stem- 

 leaves narrow, mostly entire, closely resembles 

 E. annus with which carefully compare; found 

 together in similar places, though this species 

 likes sandy and gravelly soil. Stem smaller 

 and more simple than the preceding, with 

 smaller heads but longer rays.
