w- -w- Stigmas 2 ; scales long-acute and ascending. 



38. C. salina, Wahl., var. CUSpidata, Wahl. Rather stout, l-2 

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

 what approximate, the lowest 1 or 2 very short-stalked, erect, short (1|' or less)

 awn much exceeding the perigy nium. ( 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 separated as 



C. STRATA X SAL^NA, Bailey. Spikes thinner and more scattered, more 

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

 perigynium. Near Boston, Mass., W. Boott, Morong. 

 H-t.-w.-w- Stigmas 3. 



39. C. prasina, Wahl. Slender, somewhat flexuose, 1 J -2^ high; culm 

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

 peduncled and spreading or drooping, somewhat 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, shorter than the

 southward; infrequent.

40. C. niaritima, 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 bushy, 

 usually staminate at top ; perigynium 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 

 pedunfled, mostly secund, curved and drooping (or in small forms rarely nearly 

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

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

 nerved, the minute point entire ; scale greenish-brown and rough-awned, 2-3

 narrow; spikes 3-4, ]-' long or less, less drooping; scales less prominent. 

 Maine to N. Y. ; scarce. Somewhat resembles n. 39.

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

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

 Moist meadows near the Glen House, White Mts. (Brainerd). Might be
