Spica decomposita vel paniculata ; spiculis androgynis superne sta- 

 miniferis alternis confertis permullis disiigmaticis ; fructibus oyalls 

 triquetris brevi-rostraiis vel acutlusculis parvis nigris glabris, squamam 

 ovatam acuminatam albam subaequantibus. 



Culm two or three feet high, large, triquetrous, striate, glabrous, 

 tawny below, scabrous above, leafy ; leaves linear-lanceolate, long, 

 often much surpassing the culm, distinctly nerved, rough on the edge 

 with dark and striate sheaths towards the base ; spike decompound 

 or paniculate, green ; spikelets very numerous and dense, lower 

 ones with leafy bracts arranged closely along many branchlets, sta- 

 miniferous above; stigmas two; fruit ovate, triquetrous, acute or 

 short-beaked, bidentate, black and glabrous ; pistillate scale ovate, 

 acuminate, white with a green keel, membranaceous, equalling or a 

 little surpassing the fruit. Color of the plant light green. 



Grows in Cherokee — Muh. Found abundantly by Dr. Folwell 

 in a swamp near the river Raisin, in Michigan Territory, and sent to 

 Dr. Gray of Utica, N. Y., who has obligingly sent me specimens. 



This plant has commonly been considered a variety o^C. paniculata ; 

 as such it was introduced into this Journal, Vol. X. p. 276. It is 

 however so different from that species, that it well deserves the name 

 given it by Muh. The discovery of this plant proves the correct- 

 ness of that distinguished botanist in one more particular. On C. 

 paniculata, L. the fruit is ovate-lanceolate, larger and longer, and 

 the scale is longer and narrower in proportion, and tawny on the back.
