lichens ou tho borders of ponds. (C. rigida, p. Carey; but differs in its fruit, 

 glume, loose spikes, lvs. &c.) 



124 C. granulans MuhL (B. t. Si.) 5 Spikes 2 — 4, eylindric, oblong, dense- 

 flowered, suberect ; perig. roundish-ovate, nerved, very sliort-beaked and recurve^ 

 entire at the orifice, nearly twice as long as the ovate-acuminate glume ; st. 8 — 1G', 

 orect or subdecumbent, smooth, leafy. — (Glaucous green except the mature, yellow 

 spikes. Moist soils in meadows and hedges, along brooks, abundant. 



p. recta. Perig. ovate, slightly inflated, short-acute, straight-beaked or acu- 

 minate ; in some tho lower spike3 are also long-peduncled. — S. 111. (Vasoy) 

 and La. (Hale). 



125 C. panicea L. $ Spikes 2 — 3, loose-flowered, rcmotish, lowest long-peduncu- 

 late ; pirig. subglobous, obtuse, entiro at the mouth, a little greater than the ovate, 

 subacute glume ; st. a loot high, triquetrous, leafy at tho base; lvs. shorter than 

 the stem. — Light green. Near Boston (Pickering). 



126 C. livida Tahl. $ Spike oblong; 5 spikes 2 — 3, oblong-cylindrie, sublooso- 

 flowered; psrig. ovate-oblong, subtriquetrous, subinflated, obtuse or acutish, entire 

 at the orifice ; longer than the obtuse, oblong glume; st. C — 10' high, erect, tri-

127 C. tetanica Schk., fig. 207. $ Spike3 2 — 3, oblong, loose-flowered, remote;

 tusish at tho upper and mucronato at tho lower part of tho spike; st. C — 10' high, 

 triquetrous, longer than tho flat and linear-lanceolate leaves. — Light green. Up- 

 land meadows, rare. Its recurved short beak or cramped neck (whence its name) 

 distinguishes it from C. Woodii.

 rous, longer than the broad, hyaline, green-Iceeled, rarely mucronate glume; culm 10 

 to 20', slender, stiff; lvs. very short ; plant with a close, slight pubescence, palo 

 green. — Shores of Perch Lake, &c. Jeff. Co., N. Y. (Drs. Crawo and Wood).

 towards tho base ; plant light green. — Open woods or hedges, rare. Differs frera

 9 Spikes 2 — 3, erect, 5 to lQ-flcrwered, lowest distant; perig. oval-triqvxtrous, ta-
