 erect or subdecumbent, smooth, leafy. Glaucous green except the mature, yellow- 

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



j3. RECTA. Perig. ovate, slightly inflated, short-acute, straight-beaked or nc'i',- 

 tninate; in some the lower spikes are also long-peduneled. S. 111. (Yaseyj

 late; perig. subglobous, obtuse, entire at the mouth, a little greater than the orat*, 

 subacute glume ; st, a loot high, triquetrous, leafy at the base ; Ivs. shorter than 

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

 flowered; perig. ovate-oblong, subtriquetrous, subiniiated, obtuse or acutish, entire

 triquetrous, longer than the 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.
