which are appressed to the culm ; glumes ovate, long-acuminate, nerved, 

 about two thirds as long as the fruit, reddish, with the keel green. 

 Fruit subinflated below, distinctly hairy, acuminate or rostrate, bicuspi- 

 date. 



Hab. In swamps ; Canada to Georgia ; not rare. Flowers 



in the end of May. 

 Obs. We have rarely found the sterile spikes pistilliferous 



at the summit, as they are represented by Schkuhr, but 



we have seen the upper fertile spike occasionally sterile at 



the apex. 



102. Carex verrucosa, Muhlenberg. 



C. spicis sterilibus subgeminis ; fertilibus 4 — 5, infenoribus 

 longe-pedunculatis, patulis, apice staminiferis, cylindricis ; 

 fructibus ovatis, subtriquetro-compressis, punctatis, ore 

 subbidentato, gluma ovata obtusa brevioribus. 



C. verrucosa, Muhl. gram. p. 261. Elliott sk. ii. p. 555.? 



Culm about 3 feet high, rather slender, sometimes decumbent, leafy, sca- 

 brous above. Leaves very long, glaucous, nerved, and conspicuously 

 cross-barred, scabrous on the margin, with very loose sheaths; the 

 outer ones abbreviate. Sterile spikes 2, or solitary ; terminal one ob- 

 tuse and pedunculate ; glumes oblong, obtuse or retuse, brown, with the 

 keel green. Fertile spikes mostly 5, the lower ones distant, and on 

 considerably long peduncles ; upper ones approximate and subsessile ; 

 all of them generally sterile at the summit ; glumes ovate, obtuse, brown, 

 carinate. Fruit ovate, with one conspicuous nerve, punctate under a 

 lens, but not pubescent ; rostrum minute, bifid. 



Hab. On the banks of a meadow-brook, North Carolina. 

 In Georgia and South Carolina. Muhlenberg. Flowers 

 in May. 



Obs. The C. verrucosa of Mr. Elliott, is probably the same 

 as the one we have described, though his description does 

 not apply in all respects. The name is by no means ap- 

 propriate.
