THE IOWA SEDGES. 



343 



Margins of ponds and streams; well distributed, but most 



•common in the eastern half of the state. This and the two 



preceding are very variable in regard to height of plant ; 



length of spikes, and comparative length of scales and per- 



igynia. 



Emmet countv, 1878, Crafty ; Fayette county. 1S95, Fink: 

 Johnson countv, 1895. Shimek; Charles City. Arthur; Iowa 

 City, Hitchcock; Grinnell, 1885, Norris; Scott and Musca- 

 tine counties, Barnes & Miller. 



Note. — Carex aquatilis Wahl. has been reported from Iowa, (Fink, Proc. 

 Iowa Acad. Sci., iv, 105) but there is considerable doubt regarding the 

 identification, as the plants, specimens of which are in my herbarium, are 

 in the early flowering state. It is more likely a form of C. slricta Lam. 

 Mature fruiting specimens of the plant are very much desired.

Very rare in bogs; the nodding spikes on filiform peduncles 

 give this sedge a verv graceful appearance. Also a native of 

 northern Europe.

Quite common in woods in the central and eastern portions. 

 Several specimens of this plant have been seen in Iowa col- 

 lections labelled C. miliacea Muhl. (now C. prasina Wahl.). 

 This latter species may, however, yet be found within our 

 limits, having been reported from Ramsey county, Minnesota 

 {Kossube) .
