6. CAREX IGNOTA Dewey, Sill. Jour. ser. II. viii. 348 (1849) ; 
Sartwell's Exsie, No. 97 (1848). Plant stiff but rather slender, pale 
green; culms slender, minutely scabrous on the angles above; basal 
sheaths apparently purple when young but in most cases the color 
lost through weathering; broadest basal leaves 3-5 mm. wide, stiff, 
nearly equaling the culms; broadest cauline 2-2.5 mm. wide; sheaths 
with granulose or erose angles; bracts much shorter than the culm; 
spikes widely scattered, but lower not on especially long and slender 
peduncles; staminate spikes generally peduncled, not particularly 
stout, the scales thin, narrowly oblong; anthers 2.9-3.2 mm. long 
when dry; pistillate spikes 22-32 mm. long, loosely almost alternately 
flowered, the rhachis granulose to nearly smooth; scales oblong, 
acute or subacute, cuspidate; perigynia fusiform, strongly acute at 
each end, slightly curved, obtusely angled, closely and strongly 
28-36-nerved, 4.2-5.0 mm. long. Wooded hillsides; Western Florida 
to Texas. 
This plant is related to C. striatula to which it shows a close super- 
ficial resemblance. It differs in the more slender spikes, the generally 
granulose rhachis, and the purple basal sheaths. The granulose 
nature of the rhachis is clearly evident in only about 80% of the 
specimens, and the purple sheaths are frequently difficult to make 
out because of weathering. However, the plants have a different 
aspect from those of C. striatula, which fact together with the charact- 
ers given, has led to their treatment here as a separate species.
