9. C. srYLoFLEXA Buckley, Amer. Jour. Sci. ser. IT. xlv. 174 (1843); 
Mackenzie in Britton & Brown's Ill. Flora ed. 2. C. laxiflora & 
styloflexa Boott, Ill. Carex 37. Pl. 90 (1858); Robinson & Fernald in 
Gray's Man. ed. 7.— Plants tall and slender for the group, brighter 
green, yellowish green when dry; culms 0.5-1.4 mm. in diam., more 
or less granulose-scabrous on the angles; basal sheaths brown; broad- 
est basal leaves 2.5-8 mm. wide; broadest cauline 1.8-4 mm. wide, 
mostly soft; sheaths rather close, the angles smooth or slightly 
scabrous; bracts usually shorter than the culms; spikes widely scat- 
tered, the staminate usually conspicuous and peduncled, the scales, 
thin, often brown; anthers 3.0-4.0 mm. long; pistillate spikes rather 
dense, the larger 10-15 (18) mm. long, the rhachis granular-roughened ; 
scales narrowly oblong, acute, rarely cuspidate; perigynia (35) 40-45 
mm. long, broadly ellipsoidal, stipitate, divaricate and curved out- 
ward, slender-tipped, (21) 24—33-nerved.—Low meadows and wood- 
lands: Connecticut to Florida, Kentucky, Louisiana, and Texas. 
Var. fusiformis (Chapman) comb. nov. C. fusiformis Chapman in 
Dewey, Sill. Jour. Ser. II. vi. 244 (1848). C. Chapmanii Steud. Cyp. 
Plant. 222 (1856).—Perigynia fusiform-lanceolate, straighter and more: 
ascending; scales lance-oblong.—Damp soil on hammocks: Florida. 
The specimens of this variety show some indication of being stolonif- 
erous, and the perigynia are rather characteristic. The plant may 
prove to be a distinct species. 
Var. remotifiora var. nov. Foliis perbrevibus et perangustis ; 
spicis laxiflorioribus et longioribus, perigyniis adscendentioribus; 
rhachibus sublaevibus. Leaves very short and narrow; spikes more 
loosely flowered and longer; perigynia more ascending; rhachis of 
the spikes almost or quite smooth. Alabama and northern Florida.

Chattahoochee, Florita A. H. Curtiss (Type in Herb. Bailey). 
Mackenzie (Ill. Flora ed. 2) states that the basal sheaths of C. 
styloflexa are sometimes purple, but purple color is not evident in 
any of the specimens studied by the writer.
