from the East Coast of Demerara. 403 



North America, have been named as localities where it has been 

 found growing. 



Cenchrus tribuloides, Linn. Spec. 1489 ; Michaux, Fl. Bor. Am. i. 61 ; 

 Pursh, Fl. Am. Sept. i. 60. 



This plant resembles the former in its general appearance ; it 

 is however more restricted to the sea-shore and sandy places, and 

 extends to a more northern latitude than the former. I col- 

 lected it in Demerara on the east coast, and more recently in 

 Barbados. Sellow found it in Monte Video, and the American 

 authorities above-cited prove its occurrence in the United States. 



Andropogon (Anatherum) bicornis, Linn.; Meyer, /. c. 70; Swartz, 



Obs. 382. 

 Anatherum bicorne, N. ab E. in /. c. ii. 321 ; Browne, Jamaica, p. 365; 



Sloane, Jamaica, i. 42. t. 13 ; Pursh, Fl. Am. Sept. i. 75. 



Fox-tail; Deer's-taiL 



The culm of this grass, which grows on savannahs and at the 

 sides of mountains, reaches a height of from four to five feet, and 

 is of the thickness of a goose-quill. The tufts of hair upon the 

 flowers are long, white, soft, and much finer than cotton ; they 

 are sometimes of a reddish or purplish colour. The blades are 

 too coarse to serve as fodder, but the negroes used the halms 

 formerly to thatch their houses with. Piso was informed by the 

 Indians that an infusion of the root was an antidote against 

 poison. It occurs in Brazil, Guiana, the Caribbee and Virgin 

 Islands, Jamaica (where, according to Browne, it is called Moun- 

 tain-grass), and Pursh enumerates it among his North American 

 plants from Virginia. 



Sporobolus virginicus, Kunth, /. c. i. 210. 



Vilfa virginica, Pal. de Beauv. Agrost. 16. 



Agrostis virginica, Torrey, Fl. Am. Conf. Bor. et Med. i. 89. 



Agrostis pungens, Pursh, /. c. i. 64 (excl. syn. Schreb.). 



Crab-grass of Browne. 



This elegant little grass, which is very extensively distributed, 

 resembles in its habit of creeping along the soil Paspalus vagi- 

 natus, from which circumstance Browne has named it Crab-grass 

 in his i History of Jamaica/ It is generally found on the skirts 

 of brackish water, and those specimens which have come under 

 my observation were scarcely above five or six inches in height. 

 Some specimens which I collected near the steamboat wharf 

 in Georgetown are designated by Nees von Esenbeck as S. vir- 

 ginicus, var. minor, minus glaucus. Humboldt found it near Cal- 

 lao, Truxillo and Gnamang, on the shores of the Southern Pacific, 

 and near Punta Araya and Cumana, on the Atlantic Ocean; Kunth
