loosely flowered at the base : perigynium elliptic-ovate, hairy when 

 young, abruptly contracted into a short minutely toothed beak, lightly 

 nerved, longer and broader than the very obtuse and erose-margined 

 scale. — California in the Red Mountains, Mendocino Co., Bolander

134. Carex Saskatchewana, Boeckeler, Linnaea, xli. 159. 

 Perhaps a member of this group : — " Rhizome elongated, slender, 



the fibrils long and capillary : culms several, fasciculate, strict, 

 setaceous-capillary, triangular, rough above, one and a half to two 

 inches high : leaves yellowish green, spreading, firm, linear, shortly 

 attenuate, rather obtuse, plane and striate, a line wide, roughish 

 towards the apex on the margins, the upper ones and the bracts fili- 

 form and much longer than the culm (two inches long) : spikes three 

 or four, erect, peduncled, very slender, terete, somewhat densely 

 flowered, yellowish white, before flowering approximate : staminate 

 spike linear-oblong, few-flowered, three to four lines long : pistillate 

 spikes filiform, 8 to 12-flowered, five to six lines long: peduncles 

 capillary, exserted : scales pellucid-membranaceous, white above and 

 dull yellow towards the base, the middle i^ale green, broadly ovate, 

 obtuse or slightly acute : perigynium (young) equalling the scale, 

 oblong-linear, straight, slightly attenuated, triangular, nerveless, very 

 lightly striolate, the margins lightly ciliate, whitish above and yellowish- 

 green at the base, the orifice obtuse and entire. — Saskatchewan,
