98. C. gymnoclada Holm. (Fig. 40). Loosely and strongly stoloniferous, 

 the culms phyllopodic, stiff, sharply triangular and usually roughened above, ex- 

 ceeding leaves, brownish at base; culms usually developing some very short blades 

 the first year and in the flowering (second) year 2-4 

 erect blades, 2.5-4 mm. wide, flat with revolute 

 margins; staminate spike short-peduncled, 5-15 mm. 

 long; pistillate spikes 2 or 3, approximate, sessile 

 or short-peduncled, oblong or linear-oblong, 5-15 (or 

 22) mm. long, 4-6 mm. wide, the perigynia 8-30, 

 spreading-ascending, closely packed; lowest bract 

 usually shorter than culm; scales ovate or lance- 

 olate, obtuse to acuminate, purplish-black, the mid- 

 vein usually obsolete; perigynia obovoid, plano- 

 convex, not turgid, 3 mm. long, 1.75 mm. wide, 

 straw-colored, often dark tinged, nerveless except 

 for marginal ribs, membranaceous, granular, rounded 

 at base, abruptly minutely beaked, the beak 

 straight, 0.25 mm. long.

In Carex concolor R. Br. (C. rigida Good.) and C. scopulorum Holm, which are the closest 

 allies of this species, the flowering culms develop a number of long bladed leaves the first year, which 

 persist during the second (flowering) year in a dry condition. In the present species these leaves are 

 less developed, thus giving the plants a markedly different appearance. The granular perigynia also 

 serve to separate it from Carex concolor, and the non-turgid straight-beaked perigynia from Carex 

 scopulorum. 



99. C. nebraskensis Dewey. (Fig. 41). Rootstocks creeping and stolon- 

 iferous; culms 2.5-10 dm. high, stout, rigid, roughened or smooth above; leaf-blades 

 pale green, 3-8 mm. wide, flat, the sheaths nodulose, white hyaline ventrally; stam-
