■M- -w. Stigmas 2 ; scales long-acute arid ascending. 



38. C. salina, Wahl., var. CUSpid^ta, Wahl. Rather stout, 1-2*° 

 liigh; culm rather sharp, smooth ; leaves narrow but flat; spikes 2-4, some- 

 what approximate, tlie lowest 1 or 2 very short-stalked, erect, short (l^' or less) 

 and rather thick, the lower subtended by leaf-like bracts 3-4' long; perigyn- 

 ium elliptic, somewhat granular, marked with 2 or 3 nerves or nerveless, the 

 miimte beak entire ; scale brown-margined, produced into a lighter and rough 

 awn nmch exceeding the perigynium. (C. salina, Man.) — Salt marshes, Mass., 

 and along the coast northward ; rare in the United States. (Eu.) Anomalous 

 forms, which appear to be hybrids, have been sejjarated as 



C STitfcTA X SALiXA, Kailey. Spikes thinner and more .scattered, more 

 inclined to be peduncled ; scales blunt or short-awned, little exceeding the 

 perigNiiium. — Near Boston, Mass., W. Boott, Murong.

30. C. prasina, Wahl. Slender, somewhat flexuose, 1^-2^° high; culm 

 ratlier sharp, smooth ; leaves very narrow, soft and flat, rough; spikes 2-3, 

 peduncled and spreading or drooping, somewliat approximate, green, 1-2' 

 long, narrow and loosely flowered ; perigynium pale, narrowly triangular-ovate, 

 thin, nearly nerveless, produced into a short but slender entire or minutely 

 toothed beak; scale very thin and acute, nearly colorless, sliorter than the 

 perigynium. (C. miliacea, Muhl.) — Meadows and bogs, Vt. to Mich., and 

 southward ; infrequent.

40. C. maritima, O. F. Mueller. Mostly stout, 1 - 2^° high ; culm sharp, 

 smooth or rough above ; spikes 2-6, scattered, all or all but the upper one 

 on very long weak stalks and pendulous, 1-3' long and thick and busliy, 

 usually staminate at top ; perig}'nium nearly orbicular, pale, few-nerved or 

 nerveless, the beak very short and entire or nearly so ; scale produced into a 

 greenish rough awn 3-8 times as long as the perigynium. — Salt marshes of 

 the coast, Mass., Maine, and northward ; not common. Leaves smooth, broad 

 and flat. (Eu.) 



41. C. crinita, Lam. Robust and mostly stout, 2-4° high ; culm sharp 

 and rough or sometimes smooth ; leaves about 3" broad, flat, more or less 

 rough on the nerves and margins ; spikes 3-6, somewhat scattered, all variously 

 peduncled, mostly secund, curved and droo])ing (or in small forms rarely nearly 

 erect), 1 -4' long, narrowly and evenly cylindric, compact or attenuate below, 

 often staminate at top ; perigynium ovate, thin and puncticulate, obscurely 

 nerved, the minute point entire; scale greenish-l)rown and rough-awned, 2-3

 narrow; spikes 3-4, ]V long or less, loss drooping; scal»»s less prominent. —

C. crinIta X TORTA, Railcy. More slender than C. crinita, the leaves nar- 

 rower ; spikes nearly as slender as tlio.se of C. torta ; scales blunt or simply 

 acute and little longer than the perigynium, or sometimes very short-avNiied. 

 — jNIoist meadows near the Glen House, White Mts. {Brainerd). Might be
