CONTEIBUTIONS FROM THE NATIONAL HEEBAEIUM. 



the palea is not entirely inclosed by the fertile lemma. In these characters and in 

 its inflorescence and aquatic habit it approaches Hymenachne. 



In some parts of Florida this species, known as " maiden cane," becomes a 

 troublesome weed in cultivated soil on account of the creeping rootstocks. In this 

 situation it very rarely produces flowering culms. 



DISTRIBUTION. 



In moist soil, along river banks and ditches, borders of lakes and ponds, often in 

 water, Delaware to Florida and west to Texas.
