264 North American Cyperacea. 



scarious margin. Stamrjis commonly 3. Style short, two-cleft. Nut 

 puncticulate, dark-brown, or black. 



Hab. In bogs, and also in dry soils ; South Carolina and 

 Georgia, Muhlenberg ! and Elliott ! — May to September. 



Obs. This species appears to be confined to the southern 

 states, and I doubt whether it has been found north of South 

 Carolina. It is easily distinguished by its remotely-flowered 

 spikelets, and very obtuse, almost truncated scales, with broad 

 scariou? margins. In a specimen, received from Mr. Elliott, 

 the spikelets are from twenty to thirty-flowered. Mr. E. re- 

 marks, that " In bogs it becomes a large plant, 2 — 3 feet high, 

 thick and succulent ; in dry soils, even where not sandy, it 

 rarely exceeds 12 — 15 inches in height." 



5. Cyperus Elliottianus, Schultes. 



" Spikelets ovate-oblong, many-flowered, in terminal fasci- 

 cles ; involucrum two-leaved, and with the leaves linear and 

 very narrow." 



C. Elliottianus, Schult. mant. syst. veg. 2. p. 101. 



C. fasciculatus, Elliott, sJc. 1. p. 63, (not of Lamarck.) 



*' Culm 6 inches high, triangular. Leaves 1 — 2, very nar- 

 row and almost setaceous, shorter than the culm. Involucrum 

 2-leaved, one of the leaves scarcely longer than the spikelets, the 

 other very long. Spikelets 5 — 7, all sessile, 12 — 24-flowered. 

 Scales rather obtuse : the keel deep green, the margins mem- 

 branaceous." Elliott. 



Hab. Near Milledgeville, Georgia. Dr. BoyJcin, fide 

 Elliott. 



Mr. Elliott's plant may be some larger species in a dwarf 

 state, but his description is too incomplete to distinguish it from 

 several other Cyperi. Nees, however, refers it, in his Syjiops. 

 gen. Cyp. to the genus Pycreus of P. de Beauvois, but unless 

 he has seen a specimen from Elliott himself (which is hardly 

 probable) I suspect that he has examined a different species, 

 perhaps the C. diandrus of this monograph.
