Trifolium hybridum L. 



Alsike clover 



Fields and pastures. Common. Jul}'- and August, This introduced 

 species appears to be perfectly at home here. It persists where it has 

 been planted and stubbornly refuses to yield possession of the ground to 

 those noxious and aggressive weeds that too often overpower and subdue 

 useful species. I have seen it in sheep pastures, maintaining its foothold 

 in places where it was almost surrounded by sheep sorrel. Its flowers 

 aftbrd good bee pasture and are sought by honey bees. 



Trifolium pratense L.. 



Red clover c 



Waysides and meadows. Common. July and August. This and 

 alsike clover are cultivated for fodder and furnish a considerable part of 

 the hay crop. 



Trifolium agrarium L. 



Yellow clover. Hop clover 



Pastures, clearings and roadsides. Occasional. It is an introduced 

 plant but not cultivated. Its yellow flowers easily distinguish it from 

 the other clovers. 



Melilotus alba Desv. 

 White meltlot. Sweet clover 



Waste places and roadsides. Raybrook. August. The yellow 

 melilot, Melilotus officinalis (L.) Lam., is often associated with this species. 

 Both species often grow along railroads and the yellow mehlot will 

 probably be introduced soon. The black medic, Medicago liipulina L., 

 a common introduced weed, may also be expected to make its appear- 

 ance here in the near future. 



Vicia sativa L. 



Common vetch. Tare 

 Fields and meadows. Rare. Allen farm. August. 



Vicia Cracca L. 



Tufted vetch. Cow vetch. Blue vetch 

 Roadsides. Scarce, Lake Placid and Newman. July.
