Cyperus pseudovegetus Steud. 



4. Cyperus inflexus Muhl. (Cyperus aristatus Rottb.) Map 344. In- 

 frequent in wet, sandy or muddy soil on bars in streams and ditches and 

 on the shores of lakes and borders of sloughs. Specimens of this species 

 when dried have a pleasing odor, similar to that of dried slippery elm 

 leaves. 



N. B. to B. C, southw. to Fla., Tex., Calif., and Mex. 



5. Cyperus acuminatus Torr. & Hook. Map 345. I have found this 

 species only in Crawford and Greene Counties. I am not able to locate my 

 Crawford County specimen now. Friesner also found it in Greene County. 

 Geise cites a specimen from near Chesterton, Porter County, collected by 

 E. T. Harper in 1888. This specimen is deposited in the herbarium of the 

 University of Wisconsin. I have seen it and the determination is correct. 



Ind. to N. Dak. and Wash., southw. to Ga., Tex., and Calif. 



6. Cyperus pseudovegetus Steud. Map 346. Infrequent in ditches and 

 swamps in Point Township of Posey County. It has been found also in 

 Gibson, Pike, and Jefferson Counties. Where found it is usually common. 



N. J. to Kans., southw. to Fla. and Tex. 



7. Cyperus ovularis (Michx.) Torr. Map 347. This species is found in 

 very dry to moist, sandy habitats. It is local in the southwestern coun- 

 ties. It has been reported from Lake County, but Geise did not find a 

 specimen. I believe that the Lake County report should be referred to 

 Cyperus filiculmis var. macilentus. 



N. Y. to 111. and Kans., southw. to Fla. and Tex. 



8. Cyperus filiculmis Vahl. Map 348. Fernald & Griscom discuss 

 this species and its varieties in Rhodora 37 : 153-154. 1935. If I interpret 

 their discussion correctly the distribution of this species is principally 

 on the Atlantic slope and in the Great Plains states. My only specimen
