their flattened sheaths, smooth or somewhat hairy ; spikes 2-6, the later- 

 al ones somewhat approximated near the summit of an elongate naked 

 peduncle, spreading; 2-4 inches long, smooth, except a bearded tuft at 

 their base; spikelets broadly two-awned, over one line wide. 



P ASP ALUM CILIATIFOLIUM, Michx.-(Sbiiry Slender Paspa- 

 lum). 



Perennial. With the former, flowers in August and September. Culm 

 mostly prostrate, 1-2 feet long, smoothish. Leaves about two lines 

 wide, commonly very hairy and ciliate on the margin. Peduncle of the 

 terminal spike 2-6 inches long, arising from the uppermost sheath. 

 From the same sheath usually proceeds another spike, on a much shorter 

 peduncle, but sometimes it is only partially or not at all exserted. Rha- 

 chis very narrow, convex on the back, hairy at the base. Spikelets two 

 on a short forked pedicel, which is closely appressed to the rhachis, less 

 than a line in length. Perfect flower as long as the glume, very smooth 

 and shining. 



PASPALUM DIGITABIA, Poir— {Finger-shaped Paspalum). 



Culms ascending 1-2| feet high, spikes , slender, rather 

 sparsely flowered, 1-4 inches long, both sessile at the apex 

 of the slender peduncle; spikelets ovate — lanceolate, 2 lines 

 long; common in the barrens. 



PASPALUM DISTICHUM, L,— {Joint Grass. Perennial.) 



In wet places sometimes partly submerged. Nearly glab- 

 rous, nearly glaucous; culms ascending, about one foot high 

 from a long, creeping base; leaves linear — lanceolate, spikes 

 short, 1-2 inches long, closely flowered, one shortly pedun- 

 cled, the other sessile; rhachis flat on the back; spikelets 

 ovate, slightly pointed, about lj line long. Frequent 

 around Nashville. Excellent forage; cattle very fond of it. 



Paspalum Eacemulosum and Undulatum are two species 

 resembling the former very much; the one is a perennial, 

 the other an annual, and are good pasture grasses. 



GYMNOSTICHUM HYSTKIX, Sehreb. — {Bottle-brush Grass.) 



Belongs to the tribe of Hordeaceae, of which our wheat 



and barley are also members. It bears a general resemb-
