Grass, known in Brazil by the Indian name of Capim. In the tropics there are 

 many species of grass, but they do not play so important a part as with us, 

 and do not so greatly affect the character of the landscape. But the Campos, 

 the steppes, in dry regions and in the south of Brazil, are naturally covered 

 with grass; we find the Aristida family, Cortaderia (Gynerium), Selloana, 

 Gynerium saccharoides, the "Uva grass," Bouteloua racemosa, and the 

 Andropogon or Beard-grass. The following species are valued as fodder: 

 Panicum monostachyum, Stenotaphrum glabrum, Sporobolus indicus, 

 which also yields a straw for hat-making; Bromus unioloides, Leptochloa 

 virgata, Melinie minutiflora and others. Also a species of wild barley 

 (Pariana). 133
