Chamasraphis, R. Br. 



spinescens, Poir. — Water Grass. This is a useful grass, for, 

 although its floating stems may pass often out of the 

 reach of sheep, this habit of growth has a great value, 

 for it is found near waterholes liable to become dry, and 

 as the water dries up the floating runners rest upon the 

 land, and root from the nodes, and soon cover with 

 nutritious grass spots which would otherwise be bare.
