This curious grass, originally discovered by Frederick Pursh 

 "near Egg Harbor" (probably = Beesley's Point), does not 

 range north of the New Jersey Pine Barrens, nor has it been 

 found in the western part of the State beyond the limits of this 

 region. It is plentiful in damp sandy soil among the Pines, and 

 grows profusely in the damp sand thrown up into dykes around 

 the cranberry bogs. 



The peculiarity of this grass lies in the production of sub- 

 terranean fruits scattered among the slender roots, in addition to 

 the Panicum-like spike of normal seeds, which is conspicuous 

 above ground. 



Fl. — Early August to mid-September.

t Large crab-grass, an abundant weed everywhere in cultivated and waste 

 ground. Grov/s luxuriantly on the sandy ground back of the coast dunes, 

 creeping culms reaching a length of six or eight feet; seems like a native 

 in such locations.
