Plantago halophila Bicknell. Salt Marsh Plantain. 



Plantago halophila Bicknell, Britt. Manual 1051 [VanCourtland Park, N. Y. 

 City]. — Keller and Brown 298. 



A plaintain closely related to the common weed, P. major, 

 occurs along the edge of the salt marshes. 



In the new Gray's Manual it is treated as a variety intermedia 

 Gilibert, while 'Mr. Bicknell has described it as a species P. 

 halophila, not having material necessary for a study of its re- 

 lationship, I use the latter name, which beyond question refers 

 to our plant. 



Pr. — June into October. 



^ Common Plantain, a familiar weed. 



* Ribwort, a common v/eed. 



* Large-bracted Plantain, introduced from the west.
