 Kunth, in his Enumerat. Plant, i. 50, gives St. Thomas and 



Porto Rico in the West Indies, and Mexico as habitats. The above 



variety was gathered on the savannahs near Georgetown. It is 



a small elegant grass, and is esteemed by agriculturists as a good 



fodder-grass.

Lamaha-grass, 



This excellent grass, which Mr. Garnett informs me is esteemed 

 for fodder equal to guinea-grass, grows on the banks of rivulets, 

 and reaches frequently a height of from three to four feet and 

 sometimes even six feet, the culms having the thickness of a hen's 

 quill. The distribution of the true species, although not so 

 widely spread as P. vaginatus, is nevertheless very extensive. 

 Linnaeus gives its habitat as Jamaica, and Sloane pictures a tole- 

 rable representation from the same island ; Humboldt describes 

 it from Virginia de la Popa. 



The specimens from Demerara are Fliigge' s variety /3. Schre- 

 berianus, which Ledru found in Porto Rico, Sellow in Monte Video 

 and on the banks of the Rio Grande do Sul, and Von Martius on 

 the banks of rivers in the neighbourhood of Villa Ricca and Te- 

 juco in the province of Minaes Geraes. I collected it on the road 

 which leads to the Grand Etang in the island of Grenada. Jacquin 

 gives an excellent figure of the true species ; Trinius's represen- 

 tation (t. 131) resembles the Guiana variety.
