MONOECIA TRIANDRIA. 553 



^ Stem about two feet high, thick, acutely triquetrous, very scabrous along 

 the margins near the summit. Leaves longer than the stem, channelled, 

 three to four lines wide, scabrous along the edges, the long bracteal leaves 

 scabrous ako along the midrib, nerved, with small nodosities between the 

 nerves which become conspicuous as the leaf begins to wither. Male 

 spikes long, slender, scales linear lanceolate, acute. Female spikes gene- 

 rally three, pendulous, cylindrical, on peduncles generally increasing in 

 length as they descend, inclosed at base by the amplexicaule bracteal leaf. 

 Corolla ovate, rostrate, nerved, conspicuously forked with the divisions dis- 

 posed to become revolute. Scale small, with a long, subulate, serrulate 

 pomt, at first longer than the corolla, afterwards shorter. Stigmas three. 

 Seed triquetrous. 



There is to this species sometimes a fourth female spike somewhat remote} 

 this when it occurs generally has the base of the peduncle inclosed. 



This species has usually been considered in the southern states at least, as 

 the C. Pseudo-Cyperus, but though nearly allied it does not agree entirely 

 with the character of that species; the summit is much more pointed and 

 divided than the figure in English Botany, No. 242, and it is, I think, un- 

 questionably indigenous.
