Perennial ? Stem about a foot high, very slender, branching near 

 the base, and with the whole plant glabrous. Leaves linear, flat, 1-4 

 or 5 inches long, scarcely a line wide, a little scabrous 5 sheaths 

 shorter than the joints. Flotvers in a long spike ; spikelets 2-5 

 flowered, closely apprcssed, not crowded on the spike. Valves of the 

 eal^x very acute, a little unequal, about as long as the corolla. Ex- 

 terror valve of the corolla involute, trauversely ban«Ied, terminating 

 in 3 awns ; tl^e two lateral erect, straight, shorter tlian the valve ; &c 

 intermediate longer than the corolla, bent almost horizontally, but not 

 contorted, hairy at the base ; intf^rior valve wanting, or very minute; 

 keel of the calyx and corolla, and the awn very scabrous. StamnsS, 

 Anthers purple. Stigmas white, iityles very short. 



The corolla in the plants I have seen, is so curiously banded witJi 



iightand dark grey spots not unlike the body and legS of a musquito, 



thatif I had supposed them invariable, I should have called the specie5 



fasciata.- From the preceding species, it differs by a longer corollaand 



awns, and the intermediate awn not contorted ; from the succeeding, 



by a niuch more slender habit, and smaller flowers, and in the awns, 



>vhich in the A. stricta,are all longer than the corolla, and expandingt 



Grows in the vicinity of Charleston. Common. 



Flowers September— October. Slender Jristlda.
