C. tentaciilata X hirida, Bailey, Proc. Amer. Acad. Arts and 

 Sci. xxii. 69 (1886), mostly. 



Much like some forms of C. Itcrida : Staminate spike sessile 

 or very nearly so, after the manner of C. Itipiiiiua ; pistillate 

 spikes three or four, all approximated or nearly so, or the lowest 

 separated, all sessile, erect or spreading, straight or often some- 

 what curved, densely flowered, green ; perigynium long-beaked 

 and ascending, causing the spike to lack the comose appearance 

 of C. hirida. Very like C. Itipulina X retrorsa, Dudley, but that 

 plant has shorter and much looser, scattered spikes which are yel- 

 low or straw-colored and perigynium large and very thin and soft 

 in texture, Amherst, Mass., Tuckerman, according to Boott ;

C limiila ? Gray, Man. 5th ed. 582 (1867). 



Tall and lax (i^ to 2 J^ ft. high), the leaves long and narrow; 

 staminate spike, longer peduncled ; pistillate spikes looser and 

 often longer than in the species, the perigynia never being so 

 densely packed and usually becoming browner. Lower St. Law-

 Nantucket, Morong, and southward to E. Pennsylvania. 



This plant stands midway between C, vulgaris and C. stricta. 

 From the latter it is distinguished by not growing in tufts, its nar- 

 rower and smoother leaves and very obtuse black or brown and 

 white-nerved short scales. 



^Carex Pennsylvanica, Lam., var. vespertina. 



Habitually taller than the species, very slender; staminate 

 spike commonly slimmer and usually very short-peduncled ; pis- 

 tillate spikes more separated and the lowest subtended by a leafy 

 bract from one-half inch to one inch long; perigynium mostly 

 larger, more hairy, the beak longer and stouter. Oregon, " Dry
