dilated into wings on each side, considerably divergent when ripe. Seed 

 suborbicular, compressed punctate, much smaller than its envelope. 



Hab. In wet meadows and swamps, not so common as the 

 preceding species. Flowers in May. 



Obs. This species, which has been so often confounded with 

 the preceding - , is easily distinguished from it, by attending 

 to the diagnostic character we have given ; particularly its 

 broad-winged fruit. The spikelets are nearly globose, and 

 of a yellowish color when mature. 



35. CARExfoenea, Muhlenberg. 



C. spiculis pluribus (8-10,) compositis, inferioribus distinctis, 

 superioribus confluentibus ; fructibus ovatis, acuminatis, 

 alatis, bidentatis, glumis ovatis paulo longioribus. 



C. fcenea, Muhl. gram. p. 227. Elliott sk. ii. p. 533. 



Culm about 2 feet high, obtusely triangular, scabrous near the summit, un- 

 usually thick, furrowed, leafy to the middle. Leaves 3-4 lines broad, 

 scabrous on the margin, shorter than the culm. Spikes numerous sub- 

 globose ; the lower always (and sometimes the others,) disposed in fasci- 

 cles of 3-4-5 spikelets ; upper ones alternate and approximate ; at the 

 base of the lowest fascicle, which is somewhat remote from the rest, is a 

 long foliaceous bractea, diverging almost horizontally. Glumes lanceo- 

 late, not pointed, ribbed, membranaceous, lacerately ciliate on the 

 margin, shorter than the fruit. Frwif ovate-lanceolate, distinctly winged, 

 strongly ciliate on the margin ; apex bifid, but not opening. 



Hab. Marshy grounds near Germanton, Stokes County, 

 North-Carolina. In Pennsylvania, Muhlenberg. Flowers 

 late in the season. 



Obs. This species is nearly related to C. lagopodioides. 



36. Carex cristata* t. xxv. fig. 1. 



C. spiculis pluribus, (8-15) in pseuclo-capitulum aggregatis ; 

 fructibus ovato-lanceolatis, alatis, divergentibus, margine 

 grosse serratis.
