241. Carex Brongniartii, Kunth, Euum. PL ii. 380, 

 G. hypoxanthus, Steud. Plant. Cyper. 193. 



C. gloinerata, authors, uot Thunb. 

 Distinguished from C vuJpinoidea by the looser flowered and chaffy 

 spikes, the large perigyniuna, the short and straw-colored heads (usually 

 an inch and a half or less long), and the absence (or nearly so) of 

 conspicuous bracts. The Pacific slope representative of C. vulpinoidea. 

 — Arizona; California, Kellogg & Harford 1068; wet meadows, 

 Mendocino City, Bolander 4808; Oakland Slough, Bolander 6204; 

 Oregon, Kail. Chili. 



Var. DENSA. 



G. Xalapensis, Kunth, Enum. PI. ii. 380. 



G. Hoodii, Boott, 111. 17, as to Californian specimens. 



G. Brongniartii, Boott, 111. t. 402. 



G. panicidata, W. Boott, Bot. Calif, ii. 232, not Linn. 

 Heads more dense, mostly thickest at the base (often nearly an inch 

 in width) : perigynium broad-lanceolate (much longer than in the 

 type), long beaked and very prominently nerved. — California, Palmer 

 389 (San Diego Co.), Bigelow, Brewer, and others. I suspect that 

 G. anthericoides, Presl, and most of G. Hoodii, Boott, are to be referred 

 here. 



242. Carex leiorhyncha, C. A. Meyer, Mem. Acad. St. Petersb. i. 

 t. 9. 



Aspect of ordinary forms of G. vulpinoidea : lowest bract leafy, pro- 

 longed : head interrupted, narrow, an inch to three inches long, pale : 

 perigynium oblong-ovate, membranaceous, nerved, whitish, very smooth 

 throughout, the beak sharply toothed, longer than the ovate-elliptic 

 long-mucronate one-nerved scale. — Along the coast, probably from 

 Oregon northward. Siberia. Little known in America. 



243. Carex disticha, Hudson, Fl. Angl. 403. 

 G. intermedia, Gooden. Linn. Trans, ii. 154. 

 G. modesta, Gay, Ann. Sci. Nat. x. 304. 



G. Sartwellii, Dewey, Sill. Journ. xliii. 90. 

 G. schedonautos, Steud. Plant. Cyp. 189. 

 Mostly in dry places from New York to Utah and northward into 

 British America. Europe. 



D. Arenaruf!, Kunth, Enum. PI. ii. 376 ; Tuckerman, Enum. Meth. 9. Spikes 

 longer than in the last section, linear or nearly so, aggregated into sliort, 

 almost globose heads; perigynium lanceolate or ovate-lanceolate, mostly 

 larger and more delicate in texture ; scales awn-pointed or very acute. 

 Staminate flowers variously situated.
