Qnim 1 to Ofect high, rather stout and succulent, acute ly tr'noclrous ; scabreirs 

 above, leafy. Leave* about as long as the culm, (longer when young,) broad-linear 

 or lanceolate, nerved, margin scabrous; sheaths striate, somewhat loose and mem- 

 branous. Xpikelete numerous, 6 to 12 or 15, oblong, sessile, crowded, lower onra 

 diverging. At the base of each is usually a subulate brart ; all shorter than the 

 gpikeletfl, except the lower one, which is often longer* Glumes ovate-lanceolate., 

 acuminate, scarious, shorter than the fruit. Fruit oblong-lanceolate, distinctly 

 nerved, convex and gibbous at base, tapering and plano-convex above, with a nar- 

 povr, sharp, serrulate margin, and bifid apex. 

 flab. Swamps, and low grounds: common. Fl. April. Fr. Juno.

 Spaiujanu'm-like Caiif.x. 



Culm about 2 feet high, triquetrous, striate, scabrous above, leafy towards the base. 

 Leaves broad-linear or lanceolate, flat, striate, about as long as the culm; those near 

 fhe base short ; sheaths membranous, loose, often whitish. Spikelets 6 to 10, clus- 

 rered above, 2 to 4 of the lower ones rather distant, with linear-ovate, or lance-lin- 

 «ar, scabrous bracts at base, which are sometimes longer than the spikelets. 

 (Humes ovale, mucronate. Fruit compressed, diverging and nearly horizontal, 

 nerve less or indistinctly nerved, scabrous on the margin, bidentate at apex, yel- 

 lowish when mature.

 braeteate; spikelets glomerate, ovoid-oblong, obtuse ; fruit compressed,

 Maxy-flowehed Carex. 



Culm about 2 feet high, obtusely triangular at base, triquetrous above, leafy . 

 Leaves linear-lanceolate, channelled, scabrous on the margin, the upper ones 

 taller than the culm : sheaths transversely rugose opposite the leaves. Spike de- 

 compound and somewhat paniculate, 2 to 3 inches long, formed of numerous spike- 

 lets which arc crowded into clusters a little separated from each other, and either 

 appressed to the rachis or diverging. Bracts under the spike, and principal clas- 

 ters, often long and fdiaceous; at the base of the spiktleis, short, setaceous and 

 scabrous. St amino! e glumss lanceolate, with a short point: Pistillate glumes 

 evate, with a lunger serrulate point. Fruit 3-nerved, bifid at apex, rather small, 

 densely crowded, finally much diverging and yellowish.
