In lagoons near Asuncion (281). December-January. 



This famous flower is abundant in the lagoons on the Paraguay 

 River, and is found as far south as Corrientes. The popular name 

 which it bears, ''Mais del agua,^^ is derived from the use made of 

 its seeds. These are aboQt as large as buck-shot, and are gathered 

 by the natives and roasted or pounded into meal, from which very 

 palatal)le and nutritious bread is made.
