E. ramosus (Walt.) B. 8. P. Slender Daisy Fleabane. White-top.

Found in the same situations as the preceding, but more often 

 invading woodlands. The form is not separated from annuus 

 in many cases. Mr. Blatchley says: "This species and E. annuus 

 are the most pernicious weeds with which the growers of timothy 

 or clover have to contend.''' 



Flowers from May until the late frosts.
