fourth inch wide, round pointed ; stolons compressed, about one-eighth inch 

 in diameter. 1 



This grass is seldom found north of Tennessee or North Carolina, but it is common on 

 the sandv soils of the Gulf States. 



3. Poverty grass (Danthonia spicata; fig. 7). 



A tufted perennial; leaves folded in the bud; collar narrow, continu- 

 ous, hairy ; auricles none ; ligule a fringe of short hairs ; blades often 

 curled, glabrous, rough on the under surface and margins, about one- 

 eighth inch wide, sharp pointed. 



This grass is often found on poor sandy soils. The leaves, frequently curled, form a 

 small rounded tuft.

4. Broom sedge (Andropogon virginicus; fig. S). 



A coarse, tufted perennial; leaves folded in the bud; collar small, 

 hairy, in two parts, separated in the middle by a broad gap ; auricles none ; 

 ligule membranous, hairy on the back and fringed with long hairs ; sheaths 

 much compressed, hairy along the margins, merging indistinctly into the 

 blade ; blades compressed near base, hairy along margins, about one-fourth 

 inch wide, sharp pointed. 



The remains of the previous year's growth persist as tough, woody, buff-colored tufts. 

 This grass is readily recognized by its peculiar collar, folded leaf bud, and strongly com- 

 pressed sheaths and blades. 



1 St. Augustine grass (StenotapJirum americanum) would also trace to this place. It 

 very closely resembles carpet grass when young, but differs from it in the fact that the 

 collar is very much constricted (fig. 6).
