Stem about a foot high, slender, triquetrous, pubescent near the summit. 

 Leaves narrow, rather longer thari the stem, somewhat hairy. Splices three 

 to four, the terminal sterile at base, the rest generally fertile, the lower some- 

 whit cylindrical on short peduncles. Scales of the fertile florets ovate 

 mucronate, scarcely as long as the mature fruit. Corolla ovate, nerved. 



In specimens of this plant collected near St. Mary's, by Dr. Baldwin, the 

 leaves are less hairy, and the lateral spikes more nearly sessile, than in those 

 I possess from Pennsylvania.
