COCKLEBUR. ) 
Beaches and waste places near the coast, sometimes in the interior,

Xanthium spinosum, Ll. (SPrinG CLorsur.) 
Near Flax pond, Lynn (Herbert A. Young, C. E. Faxon). ‘ Intro-

it is likely to become troublesome. Ina letter written July 15, 1875, 
the late Dr. Chas. Pickering says ‘‘ R. hirta has entered Essex county 
since I left in 1826. It was observed in Pennsylvania by Muhlen- 
berg, by myself near Philadelphia, and is entered on my Catalogue 
(finished in 1837) as not north of lat. 40°. How far the invasion is 
attributable to the removal of the forest remains an open question.’

places afew seasons. (Int. from Trop. Am.)

Coreopsis tinctoria, Nutt.

taneously in a field in Wenham, 1876 (Mrs. M. W. Kimball). 
Coreopsis trichosperma, Michz. (TicksEED SUNFLOWER.) 
**Occasional in Lynn” (Tracy). Very common in many other
