 (1° high) and the broad fat leaves smooth. (C. palcacea, Wahl.) — Coast of 

 Massachusetts and northward ; rare. (Eu.) 



51. C. crinifa, Lam. Sterile spikes 1-2, often with fertile flowers various- 

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

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

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

 the oblong roughly-awned light-brown scale; culm (2° -4° high) rough and sharply 

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

 With the awns of the scales vert/ lone; and the fruit imperfect (var. MORBIDA, 

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

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

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



•.- •*- Stigmas 3 : perigynium obtusely triangular, indistinctly few-nerved, more 

 or less compressed : pistillate spikts borne on exserkd filiform drooping stalks. —

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

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

 shorter than the culm; sheaths obsolete or minute; perigynia roundish-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, Scop. C. reenrva, Iluds. C. Barrattii, 

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

 A widely variable species. (Eu.) 



53. C. llIHOSa, L. Staminate spike solitary ; the firti/e 1 -2, oblong, 10- 

 20-fioivered, 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 mucronate scale. — Peat-bogs, New England to Pennsylvania, 

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

 and rigid leaves. (Eu.) 



54. C. ifi'B'iglia, 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 tJie culm ; perigynia 

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

 (C. limosa, var. irrigua, Wahl. C. paupercuia, Michx.) — Peat-bogs, New Eng- 

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

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



# * Uppermost spike 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. — AtrItje.* 



55. C. BuxbaiilBtlii, Wahl. Spikes 3-4, obovoid or oblong, the uppermost 

 short-stalked (rarely altogether staminate), the others nearly sessile, the lowest sonie- 



* C. Vahlii, Schk., of this group, occurs on the north shore of Lake Superior and on Isle
