brevi-aristata ; foliis li- | or with a short awn ; 

 neaiibus, planis. E. | leaves linear, flat. 



Perennial ? Stem 2 — 3 feet liighj glabrous, columnar. Leav^^$ 

 8 — 12 inches long, scarcely I line wide, flat, scabrous ; sheath j;la- 

 brous; stipules !png, membranous. Fanicle nearly a foot long, dif- 

 fused. Feduncles long, capillary, Valves of t\\Q calyx a little un- 

 equal, half as long as the corolla, membranous. Exteriov valu of 

 the corolla terminated by a short, straight awn ; the interior some- 

 times I line longer than the exterior, excluding the awn. 



A coarse rush-like grass, growing in sandy woods and pasture?, 

 forming detached tufts. If the flower had permitted, I should have 

 refered the A. juncea of Michaux to this species. 



Found in Chatham county, Georgia, by Dr. Baldwin. Near Charle?- 

 ton. I believe it is very common in poor, dry soils. 



Flowers September — October. Ualr-j)anicled Jp't^slh.

Growls around Charleston; rare, perhaps imported. I shouiil Ij^ ^ 

 referred it to A. dispar, Mich, but its size, and the almost equal va/t ' 

 of the corolla forbade.
