Polygonum dumetorum L. Sheffield (Walters). 



Alliaria officinalis Andrz. Pittsfield (Lincoln). 



Cuscuta Coryli Engelm. Mt. Washington (Stetson).

Solidago erecta Pursh. Mt. Washington (Stetson). 



Doubtful Species. 



Panicum lucidum Ashe. A specimen from rocky woods of Great Barrington, 

 which Mrs. Chase thinks may be P. lucidum, but a vernal form which is not 

 entirely characteristic. 



P. meridionale Ashe. — A doubtful specimen from edge of low meadow in 

 poor soil, Sheffield. 



Asclepias purpurascens L. — Material collected in fruit in sandy ground near 

 the Housatonic River in Stockbridge in 1920, probably belongs to this species. 

 There has been no opportunity to verify by material in flower.
