 with the awns of the scales very long and the fruit imperfect (var. morbida, 

 Carey in Sill. Jour. & C. paleacea, Amer. auth., not of Wahl.) ; and with awns

 borders of rills ; very common. — A variable but easily recognized species.

52. C. fldcca, Schreb. Sterile spikes 1 - 2 ; the fertile about S, cylindrical, 

 on exserted drooping stalks, commonly staminate at the tojj; lower bract usually 

 shorter than the culm ; sheaths obsolete or minute ; perigynia roundish-oi'oid, 

 notched at the point, smooth or slightly roughened an the angles, about the length of 

 the obtuse or pointed black scale ; culm sharply triangular, rough, taller than the 

 glaucous rigid leaves. (C. glauca, Scop. C. recurva, Huds. C. Barrattii, 

 Schw. ^ Torr.) — Marshes of New Jersey, near the coast, Collins, Knieskern. — 

 A widely variable species. (Eu.)

 20-flowered, occasionally with staminate flowers at the apex ; bracts very narrow, 

 the lowest shorter than the culm ; perigynia ovate, With a minute entire point, about 

 equal to the ovate muavnate scale. — Poat-bogs, New England to Pennsylvania, 

 Wisconsin, and northward. — Culm 6'- 12' high, erect, longer than the sharp

54. C. irrigua, Smith. Staminate spike solitary; the fertile 2-4, ovoid 

 or oblong, occasionally staminate at the apex, or rarely with a few sterile flowers 

 at the base ; lowest bract as wide as the leaves, longer- than the culm ; perigynia 

 roundish-ovate, with an entire orifice, much shorter than the tapering pointed scale. 

 (C. limosa, var. irrigua, WaU. C. panpercula, Miclix.) — Peat^bogs, New Eng- 

 land to Penn., Wisconsin, and northward. — Taller than the last, growing iu 

 clumps, with weaker nodding stems, often exceeded by the leaves. (Eu.) 



# * Uppermost spike club-shaped, pistillate above and staminate at the base ; the rest
