lose. They are apparently similar to R. polyphylla, VahL 

 (Mitrospora, Nees.) 



This plant was sent me a year or two since from the Santee 

 by Mr. Ravenel. I am indebted to Mr. Carey for the mss. name 

 of Dr. Chapman, which I have adopted instead of the one I 

 had intended, (R. Ravenelii,) and under which I have distrib- 

 uted it. 



The last two species, with R. pusilla, are peculiar among the 

 North American species in the absence of hypogynous bristles ; 

 but they differ so much in habit that they can hardly be arranged 

 together with reference only to this circumstance. R. divergens 

 appears to be uniformly monandrous. 



Carex glaucescens, Ell. y. polystachya. — Spikes 8-12, 

 small, nodding, mostly staminate at the summit. — Society Hill, 

 S. Car., by the margins of ponds. This, like var. androgyna, 

 (described in vol. xliv of this Journal,) is an autumnal variety, 

 but much smaller and less showy than the other forms, and ap- 

 parently produced by having been cropped early in the season by 

 cattle.

ticipated by Schweinitz in the discovery of this and the follow- 

 ing species. To this he had given the mss. name of C. Dar- 

 lingtonii, which I regret it should not have borne, in honor of 

 the excellent botanist for whom it was named. 



C. Mitchelliana, M. A. C. — This was also indicated by 

 Schweinitz as new, but not named. Both of them were proba- 

 bly collected in the western part of N. Carolina. 



C. styloflexa, Buckley t — Lower and middle region of N. 

 Car., quite common. I have it also from Louisiana and Florida, 

 and I think the same was gathered by Richardson in British 

 America. It is to me a doubtful species. 



C. torta, Boott — Mountains of N, Carolina. 



C. flacca, Schreb.— Raleigh, N. Car. Also in Alabama!

Culm 3-4 ft. high, stout but rather flaccid, smooth, striate, hol- 

 low. Submersed nodes radiculate. Submerged sheaths leafless, 

 loose, shorter than the nodes, the upper sheaths longer. Ligule a 

 fimbriate margin. Leaves 6-8 in. Ions:. 5-6 lines wide, rather
