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 also 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 lon£, subulate, serrulate 
point, 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.

Stem about two feet high, triquetrous, glabrous, the margins near the sum- 
mit slightly roughened. Leaves narrow, channelled, acutely serrulate, the 
lower conspicuously glaucous, shorter than the stem. Sterile spike cylin- 
drical, solitary, pedunculate, scales ovate, emarginate, mucronate, ferrugi- 
nous with the midrib green. Fertile spikes on slender peduncles one to 
three inches long, not enclosed at base, becoming pendulous as the fruit ma- 
tures, scales ovate, deeply emarginate, mucronate, ferruginous with the mid- 
rib green. Corolla ovate, with a very short two-cleft mouth, very glaucous, 
the nerves excepting the two lateral ones indistinct, much longer than the 
blade of the scales and nearly as long as the mucronate point. Seed trique- 
trous.
