This species grows in Pennsylvania, New York, and New Eng- 

 land. Mr. C. Gr. Pringle sends it from Vermont growing on dry 

 hillocks along the Waterbury River. It also grows on the summit 

 of the Roan Mountains, North Carolina, over large areas, and fur- 

 nishes good summer pasturage. Probably it occurs on the other 

 mountains of the Alleghany range.

Cynodon, Pers. 



Spikek'ts sessile in two rows on one side of the slender spikes,, 

 which are digitate at the end of the peduncle or culm ; one-flowered,, 

 with a short pediceled, naked rudiment of a second flower ; outer 

 glumes nearly equal, keeled ; flowering glume boat-shaped, broader,, 

 prominently keeled ; palet narrower, prominently two-keeled. 

 1. C. dactylon, Pers. Bermuda grass. Naturalized and cultivated. 



A low, creeping perennial grass, with abundant short leaves at 

 the base, sending up slender, nearly leafless flower stalks or culms,, 

 which have three to five slender, diverging spikes at the summit. 

 The spikelets are sessile in two rows on one side of the slender 

 spikes ; they each have one flower, with a short, pediceled, naked 

 rudiment of a second flowei' ; the outer glumes nearly equal, keeled; 

 the flowering glume boat-shaped, broader, and prominently keeled ; 

 the palet narrow and two-keeled. This grass is a native of Southern 

 Europe and of all tropical countries. It is a common pasture grass 

 in the West Indies. In the Southern States it has long been a chief 

 reliance for pasture, has been extravagantly praised by some, and 

 cursed by others who find it difficult to eradicate when once estab- 

 lished. Its properties have been very fully discussed in Southern 

 journals. It rarely ripens any seed, and the usual methods of re- 

 producing is to chop up the roots with a cutting knife, sow them, 

 broadcast, and plow under shallow. 



Col. T. C. Howard, of Georgia, says : 



The desideratum to the South is a grass that is perennial, nutritious, and adapted 

 to the climate. While we have grasses and forage plants that do well when nursed, 

 we have few that live and thrive here as in their native habitat. The Bermuda and.
