51. C. crilllta, Lam. Sterile spikes 1-2, often with fertile flouxrs various- 

 ly intermixed; the fertile 3-5, long-cylindrical (2'-3' long), densely flowertd, on 

 exserted nodding stalks ; bracts very long, exceeding the culm ; perigynia roundish- 

 ibovate, slightly inflated, obscurely nerved, with a short entire point, shorter than 

 the oblong roughly-owned ligld-brown scale; adai (2-4 high) rough and s/arplj 

 angled, leafy below; the pale leaves 3" -4" wide, also rough-edged. Varies, 

 with the awns of the scales ray long and the fruit imperfect (var. MORBIDA, 

 Carey in SSI. Jour. & C. paleacea, Amur. auth. t not of Wahl.) ; and with awns 

 not much longer than the scales (C. gynandra, Sdiw.). Wet meadows and 

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

 -r- - Stigmas 3 : perigynium obtusely triangular, indistinctly few-nerved, more 



or less compressed : "pistillate spikts borne on exserted filiform drooping stalks. 



52. C. flacca, Schreb. Sterile spikes 1 -2 ; the fertile about 3, cylindrical, 

 on exserted drooping stalks, conunonly dominate at the top; lower bract usually 

 shorter than the culm; sheaths obsolete or minute; perigynia rovndislt-ocoid, 

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

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

 glaucous rigid leaves. (C. glauca, Soap. C. recurra, Hmds. C. Barrattii, 

 Sduc. & Torr.) Marshes of New Jersey, near the coast, CoUins, Kjdesken. 

 A widely variable species. (Eu.) 



53. C. limosa. L. Staminate spike solitary ; the fertile 1-2, oUong, 10 - 

 2O-/oicw/, occasionally with staminate flowers at the apex; bracts very narrow, 

 the lowest shorter than the adm; perigynia ocate, with a minute entire point, abottt 

 equal to the ovate mueronate scale, Peatrbogs, New England to Pennsylvania, 

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

 and rigid leaves. (En.) 



54. C. irrigtta, 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 ; louxst bract as wide as the kaaes, longer than the adm; perigynia 

 rmmdigh-onOe, with an entire orifice, much shorter than the tapering pointed scale. 

 (C. limosa, var. irrigna, Wahl. C. paupercula, Michx.) Peatbogs, New Bag- 

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

 dumps, with weaker nodding stems, often exceeded by the leaves. (Eo.) 



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

 all fertile, or with a few sterile flowers below : lowest bract leaf-like, scarcely 

 equalling the culm, with minute light-brown auricles and no sheaths : culm 

 and leaves of a pale glaucous-green. Amlx^.*
