tibous blongis, subtriquetris, scabriusculis, ore subintegro. 

 gluma ovato-lanceolata paulo brevioribus ; foliis glaucis. 

 C. littoralis, Schw. an. tab. 1. c. 



Culm about a foot high, leafy, rather rigid, triquetrous. Leaves erect, 

 very glaucous, remarkably smooth, even on the margin, shorter than 

 the culm. Sterile spikes 2 ; upper one oblong, densely flowered ; glumes 

 ovate, obtuse, dark brown, not carinate. Fertile spikes about 3, an 

 inch or more in length, rather loose-flowered, the two lowest on pretty 

 Jong filiform peduncles, which appear to be cernuous ; sheaths and up- 

 per bractese nearly obliterated ; glumes ovate-lanceolate, rather obtuse, 

 dark brown, not carinate, a little longer than the fruit, concave. Fruit 

 oblong, with a short rostrum. 



Hab. On the sea coast of New-Jersey near Cape May. 



Obs. This appears to be quite a distinct species, not hither- 

 to described. For our specimens we are indebted to our 

 excellent friend and learned botanist, Z. Collins, Esq. of 

 Philadelphia. It appears to be allied to C. panicea.

 or two inches long, the terminal one pedunculate, all of them supported 

 on a common elongated peduncle, sometimes bearing a few fertile 

 florets at the summit ; glumes obovate, obtuse or mucronate, carinate.
