shining, striate, inflated whin mature, scarcely beaked, orifice minutely bidentatc- 

 Seed triquetrous, puncticulatc. Plant glaucous. 



Bab. Shaded swamps, and wet meadows: frequent. Ft. May. Fr. July. 



29. C. gran'ulaius, JMuhl. Staminatc spike sessile, or short peclim- 

 culate ; pistillate spikelets about 3, remote, cylindric, dense-flowered, the 

 uppermost subscssilc, the lowest on a long peduncle; fruit globose- 

 ovoid, nerved, beak very short, recurved, orifice entire. Beck, Bot. p. 

 440. Specim. Gray, Gram. 2. no. 183. 

 Granular, or round-fruited Cakex. 



Culm 9 to 15 inches high, sleuder, triquetrous, smooth, leafy. Leaves linear- 

 lanceolate, erect, rather glaucous, scabrous on the margin, lower ones shorter than 

 the culm, upper ones, or bracts, surpassing the culm : sheaths white and membran- 

 aceous opposite the leaves. Staminate spikelet about threo -fourths of an inch 

 long, sometimes pedunculate, but usually closely sessile at the base of the upper 

 pistillate spikelet ; glumes lance-ovate, rather acute. Pistillate spikelets usually 3, 

 often 4, cylindric and densely fruited ; the uppermost sessile, (frequently, when 

 rh«re arc 4, the two upper ones are approximate and sessile,) the next on an ex- 

 sort peduncle, the lowest distant and long-pedunculate; glumes broad-orate, acu- 

 minate, membranaceous, shorter than the fruit. Fruit roundish-ovoid, distinctly 

 nerved, sin >oth, with a very short, somewhat gibbous and recurved beak. Seed 

 triquetrous, puncticulate. 



Hab. Wet meadows: Charlcstown : not common. FU May. Ft. July. 

 Obs. Found in Charlestown township, by D. Townsend, Esq. in 1829. 



30. C. flex cos a, Muhl. Staminatc spikelet narrow-linear, on a 

 short peduncle j pistillate spikelets about 4, slender, somewhat pendu- 

 lous, on filiform peduncles; fruit alternate, rather distant on the racing 

 oblong-lanceolate, acute at each end, smooth, about twice as long as the 

 lanceolate glume. Beck, Bot. p. 441. 

 C. debilis. Mx. Am. 2. p. 172. Not of Forster. 

 Flkxuose Carex, 



Culm 1 to 2 feet high, slender, often procumbent in age, somewhat sonorous at 

 summit and near the joints, leafy. Leaves lance-linear, narrow, soabrous on the 

 margin, upper ones equalling the culm, lower ones shorter. Sterile spikelet vcrv 

 narrow, on a short filiform peduncle, rarely bearing a few pistillate florets at sum- 

 mit ; glumes lanceolate, rather obtuse. Pistillate spikelets 3 to 5, an inch and a half 

 to two inches long, usually 3 somewhat approximate near the summit, and 1 or 2 

 distant below, nodding on filiform exserted peduncles ; rachis &l length flexuosc, 

 and not entirely concealed by the fruit; glumes lanceolate, acute, or niucronate, 

 membranaceous, about half as long as the fruit. Fruit subtriquetrous, oblong-lan- 

 ceolate, acuminate, with a slender beak, bifid at apex, nerved, smooth, at firs' 

 green, finally chesnut brown. Seed triquetrous, puncticulate. 

 Hub. Moist woodlands, and low grounds : frequent. FL June. Fr. Aug.

 sometimes with fruit at summit; pistillate spikelets mostly 3, elongated' 

 oy limine, Blender, the uppermost one subsessile, the others noddin* on
