Pine Barrens.— Toms River, Prospertown, Forked River (S), Atco (P), 

 Speedwell (S), Chatsworth, Buena Vista, Parkdale (S), Hammonton, Quaker 

 Bridge, Egg Harbor City. 



One specimen in the Academy herbarium is marked "Atlantic City, C. A. 

 Boice." It seems probable, however, that it came from the mainland west of 

 Atlantic City, and not from the island beach, as we have no definite evidence 

 of its occurrence on the coast, and it would seem very unlikely.

* Deschampsia caspitosa Linnaeus. 



{Aira caspitosa Linnaeus, Sp. Pi. 64. 1753 [Europe]). 



The only evidence of the occurrence of this grass within our limits is Dr. 

 Knieskern's statement that it occurs in "damp places" in Ocean and Mon- 

 mouth Counties "rare." I have seen no specimens. To the north it has been 

 found along the Delaware above the Water Gap.
