 Milford (Eames), Salisbury (Mrs. C. S. Phelps).

CYPERACEAE. SEDGE FAMILY. 



A large family, composed mostly of grass-like plants that are 

 found in various situations, but are specially abundant in low 

 grounds and often form nearly the entire vegetation in wet mead- 

 ows and open bogs. While they are often cut for coarse hay and 

 bedding for stock, they are of little economic value, and should 

 be rooted out and replaced where possible by species of true 

 grasses that will thrive in such locations. The dates given in 

 this family are for the time of fruiting, not of flowering, as speci- 

 mens should be collected when in fruit, it being impossible 

 otherwise in some groups to determine the exact species. 



CYPERUS L. Galingale. 



Cyperus diandrus Torr. (two-stamened). 



Frequent. Moist, grassy places and about swamps. Aug. 

 — Sept. 



Cyperus rivularis Kunth (of streams).
