61. C. hystricina, Muhl. Fertile spikes 3, oblong or cylindrical, on nod- 
ding peduncles; perigynia oblong-ovate, many-nerved, spreading, tapering into 
a minutely 2-cleft beak, twice as long as the oblong awned scale; nut obovate, 
smooth. — Swamps, Georgia, and northward.— Culms 19-13? high, rough 
ahpve, shorter than the leaves and bracts. Spikes 1/— 13! long. 
62. C. tentaculata, Muhl Sterile spike nearly sessile; fertile spikes 1 - 
3, sessile, approximate, or the lowest remote and short-peduncled, ovate or cylin- 
drical-oblong ; perigynia ovate, spreading, few-nerved, the long subulate beak 
cleft on the inner side, and minutely 2-toothed, twice as long as the lanceolate 
awned scale; nut ovoid, roughish . — Meadows and low PNE" 
northward. — Culms 1°- 13? high. - Leaves and bracts elongated. ~ 
63. C. gigantea, Rudge. Fertile spikes 3-4, oblong or cylindrical ; ‘the 
upper approximate and nearly sessile, the lowest distant and short-peduncled, 
erect; perigynia (6 —7" long) widely spreading, strongly many-nerved, taper- 
ing from an ovate and obtuse base into a long subulate rough 2-cleft beak, with 
hispid teeth, twice as long as the oblong awn-pointed scale; nut depressed, 3- 
angled. — Pine-barren ponds, Florida to South Carolina, and westward. — Culms 
29 high, smooth, shorter than the broad linear leaves and bracts. 
64. C. lupulina, Muhl. Fertile spikes 3-4, approximate, sessile, or the 
lowest short-peduncled, erect, oblong, thick (1'in diameter); perigynia (6-7" 
long) erect-spreading, tapering from the ovoid acutish base into a subulate smooth 
or slightly roughened beak, with smooth and spreading teeth, twice as long as 
the oblong awn-pointed scale; nut rhombic-oblong. — Daa Flori- 
da, and northward. — Culms and leaves as in the preceding. — 
65. C. Halei, Carey. Sterile spike slender, long-peduncled ; fertile spikes 
2 — 8, remote, ovoid or oblong (1' in diameter), erect, the lowest commonly on a 
partly exserted peduncle, the others nearly sessile; perigynia large (6" long), 
tapering from a greatly inflated and rounded base into a smooth and slender 2- 
cleft beak, with smooth and spreading teeth, more than twice as long as the ob- 
long acuminate scale ; nut rhomboid. — Banks of the Apalachicola River, Florida, 
and westward. — Culms 1° high, smooth and slender, as long as the narrow
