scales broadly ovate, each contracted into a rough awn, the lower longer than the peri- 
gynia, the upper shorter than or equalling them: perigynia oblong, obtusely 3-angled, 
acute, beakless, 2-3 mm. long, about 1 mm. thick, the orifice entire. 
In meadows, Nova Scotia to Ontario, Rhode Island, New Jersey, the mountains of North Carolina 
(according to Chapman), Ohio and Iowa. Spring. 
59. Carex oligocárpa Schk. Stems and scapes very slender or almost filiform, 
roughish, 2-5 dm. long: leaf-blades about 2 mm. wide, soft: bracts similar to the leaves : 
staminate spike long-stalked or nearly sessile: pistillate spikes 2-4, erect or nearly so,

mm. long, each narrowed into a short entire beak.

the Indian Territory and Kansas. Spring and summer. 
60. Carex polymórpha Muhl. Rather dark green. Stems and scapes stiff, 2-6 dm. 
tall: leaf-blades 3-4 mm. wide, nearly erect : bracts usually little longer than the pistillate

short-stalked or sessile, 2-4 cm. long, 8 mm. thick: scales red-brown, somewhat shorter 
than the perigynia: perigynia ovoid-oblong, obscurely 3-angled, fully 4 mm. long and 2 
mm. in diameter, the beak more than 4 as long as the body, the orifice oblique.
