CYPERACEAE 209 
22. Carex Jodrii Bailey. Stems and scapes about 6 dm. tall, scabrous, sharply 
angled: leaves surpassing the stem ; blades narrowly linear, slightly keeled, with rough 
margins : bracts mostly setaceous, without sheaths, the lower 1 or 2 surpassing the sub- 
tended spikes: staminate spike terminal: pistillate spikes remote from the staminate, 
often 5 or 6, dense, cylindric, 2.5-5 cm. long, erect or slightly spreading, slender-pe- 
duncled: scales hyaline, the serrate awns about as long as the perigynia: perigynia dark- 
colored, short-obovoid, nearly terete, granular, strongly many-nerved, each abruptly con- 
tracted into a beak about 4 as long as the body. i 
In the Comite swamp, Baton Rouge, Louisiana. Summer. 
23. Carex vestita Willd. Stems and scapes strict and slender, 4-8 dm. tall, rough 
above: leaves not overtopping the scape; blades 3-5 mm. wide: bracts similar, but nar- 
rower, short, rough-ciliate: staminate spike usually solitary, almost sessile: pistillate 
spikes 1-5, oblong, 1-2 em. long, 6-8 mm. in diameter, erect, commonly staminate at the 
summit, sessile, or the lower ones short-stalked: perigynia ovoid, densely pubescent, less 
than 2 mm. in diameter, prominently few-ribbed, each tapering gradually into a short conic 
Ud whitish beak, slightly shorter than or equalling the ovate, acute, membranous 
scales. 
In sandy woods, New Hampshire to}Pennsylvania and Georgia. Summer. 
24. Carex Walteriana Bailey. Stems and scapes slender, strict, usually rough 
above, 3-8 dm. tall: leaves not overtopping the scape; blades narrow, elongated, 2-4 
mm. wide, nodulose : lowest bract similar, the upper smaller, often almost filiform : stam- 
inate spikes 2-5, long-stalked : pistillate spikes 1 or 2, when 2 the lower one remote from 
the upper, sessile or short-stalked, oblong-cylindrie, erect, 2-4 cm. long, about 8 mm. in 
diameter, rather loosely many-flowered : scales ovate, acute, short-aristate or obtuse, mem- 
branous, 3 the length of the perigynia: perigynia ovoid, purple-brown, many-nerved, 
slightly inflated, glabrous or pubescent, 3 mm. in diameter, each tapering into a short 
2-toothed beak. [C. striata Michx.] 
In pine-land bogs, southern New Jersey to Florida. Spring and summer. 
25. Carex lanugindsa Michx. Stems and scapes slender, but usually rather stouter 
than those of C. filiformis, sharp-angled and rough above. Leaves and the lower bracts 
elongated ; blades not involute, 2-4 mm. wide, sometimes overtopping the scapes: stam- 
inate spikes 1-3, long-stalked, sometimes pistillate at the base: pistillate spikes 1-3, 
usually distant, sessile or the lower slender-stalked, cylindric, 5-6 mm. in diameter: 
scales acuminate or aristate. 
In swamps and wet meadows, Nova Scotia to British Columbia, south to New Jersey, North Caro- 
lina (according to Torrey), Kansas, New Mexico and California. Summer. 
26. Carex filifórmis L. Stems and scapes very slender, erect or reclining, smooth, 
obtusely angled, 5-9 dm. long. Leaf-blades very narrow, involute, about 2 mm. wide, 
rough margined, not overtopping the scape : lower bracts similar to the leaves, upper bracts 
filiform : flowers occasionally dioecious: staminate spikes 1-3, commonly 2, stalked : pistil- 
late spikes 1-3, cylindric, 1.5-2 cm. long, about 6 mm. in diameter, erect, sessile, or the 
lower distant and short-peduncled : scales ovate, membranous, acute or short-awned, shorter 
than or equalling the perigynia: perigynia green, ascending, oval, densely pubescent, 
faintly nerved, about 2 mm. in diameter, each tapering into a short 2-toothed beak. 
In wet meadows and swamps, Newfoundland to British Columbia, New Jersey, Pennsylvania, 
South Carolina (according to Torrey) and Iowa. Alsoin Europe. Summer. 
27. Carex hírta L. Stems and scapes rather slender, nearly smooth, 1.5-4 dm. tall : 
leaf-blades flat, pubescent, but mostly less densely so than the sheaths, 3-5 mm. wide, the 
basal ones much elongated, the upper, and the similar bracts, shorter : staminate spikes 2 or 
3, stalked : pistillate spikes 2 or 3, remote, erect, oblong-cylindric, 2-3 cm. long, about 6 
mm. in diameter : scales lanceolate, aristate, 3-nerved, shorter than the perigynia: peri- 
gynia ovoid-oblong, green, densely pubescent, 2 mm. in diameter, 4 mm. long, few-ribbed, 
each tapering into a prominently 2-toothed beak, the teeth often as long as the beak. 
In fields and waste places, Massachusetts to eastern New York, Pennsylvania and Tennessee. 
Naturalized or adventive from Europe. Summer and fall. 
28. Carex fásca All. Stems and scapes slender, stiff, cies pus rough above, 
3-9 dm. tall: leaves rough; blades erect, 2-4 mm. wide: spikes 2-4, oblong or cylindric, 
erect, all?sessile and close together, or the lowest sometimes distant and short-stalked, 
8-37 mm. long, about 8 mm. in diameter, the terminal one staminate at the base or rarely 
throughout: scales ovate, awn-tipped, black or dark brown with a green midvein, longer 
than the perigynia : perigynia elliptic or obovate, flat, ascending, 2 mm. long, light green, 
faintly few-nerved, beakless, the apex minutely 2-toothed. [C. Burbaumii Wahl.] 
In bogs, Newfoundland to Alaska, south to Georgia, Kentucky, Utah and California. Also in 
TR Peien and summer.
