sessile ; glumes light brown or yellowish : fertile spikes 5 — 6, situate as 

 the sterile, but shorter and more obtuse ; glumes greenish-yellow, almost 

 of the size of the fruit ; at the base of the lowest spike is a short brac~ 

 tea, which is often wanting. Fruit triquetrous and compressed, acu- 

 minate, and with the summit bicuspidate, smooth. Stigmas 2. 



Hab. In marshes, Pennsylvania. Flowers in May. Muh- 

 lenberg. In the Cherokee country. 



I have never met with this species either in Pennsylvania or 

 in North Carolina, and am inclined to suspect that par- 

 ticular states of C. varia, in which the fertile spikes are 

 occasionally very inconspicuous, have sometimes been 

 mistaken for it ; but the plural number of the sterile spikes 

 will always distinguish it.

Jloot creeping. Culm 3 — 6 inches high, clothed at the base with dark 

 brown sheaths, nearly terete, smooth. Leaves linear, flat, about a line

 oblong-cylindrical, acute, half an inch or more in length ; glumes dark 

 brown, acute, minutely ciliate. Fertile spikes not seen. 



Hab. In the woody country of Arctic America. Dr. Richard-

Obs. This species is nearly allied to C. dioica. Dr. Torrey 

 possesses specimens presented him by Dr. Richardson, col- 

 lected by that enterprising naturalist during his arduous 

 journey with Capt. Franklin. There are no fertile spikes 

 among them. The name given to this species by Michaux, 

 was changed to C. Michauxii m the Analytical Table
