ovale, compressed, marinate, nerved or nerveless ; rjhjx acuminate, bifid, serru- 



late on the margin. Seed ovale. 



flab. Grassy, open woodlands, and hill sides: frequent Ft. May. Ft July. 



f \ Spihclcts distinct: Stigmas 2. * Summit Staminate. 



4. C. rosea, Schkn Spikelete 4 to 6, remote, about 9-flowered, the low- 

 est one with a setaceous bract often overtopping the culm ; fruit com- 

 pressed, ovate, acuminate, marginate, diverging and radiate, nearly

 Rose Cari:x. 



Culm erect or decumbent, to 18 inches long, slender, 3 or 5 aneled, leafy near 

 ihe base. Leaves linear, narrow, often as long and even longer than the culm: 

 the sheaths at base leafless, or w iih very short leavrs. Spikclcts 3 or 4 to 6; the 

 lower ones nearly an inch remote from each other, the two upper ones closely ap- 

 proximated; each 9 to lMlowered, of which but one or two at the sumn.it arc slam- 

 inate and deciduous. GIujucs about half as long as the fruit, sometimes obtuse, 

 generally acute, and often mucronate. Fruit a little concave on the inner side, 

 with an acute margin, which it somewhat incurved, ami scabrous on the edge. 



Flah. Moist woodlands, ami low grounds: frequent. Ft. May. Fr. Jtdy. 



Obs. Dr. Muhlenberg suspected his C. retrqflexa might l e a tar, ol this; and it 

 is given as a synonym by Dr. Gray, /. c— though Prof. Dewey is cf opinion it is 

 sufficiently distinct. 



5. C. MiTULExnrnoii, Schk. Spikclcts about 5, ovoid, obtuse, alter- 

 nate, crowded at the summit of the culm, bracteatc at base ; fruit broad- 

 ovate, compressed, nerved, marginate, somewhat diverging, rather short- 

 er than the ovate mucronate glume. Beck, Hot. p. 432.

Culm 1 to 2 feet hlg&J triamrular, striate, scabrous on the angles above, smooth 

 and leafy below. Leaves linear-lanceolate, keeled, nerved, scabrous on the margin, 

 about as long as the culm, lower ones short ; sheaths striate, scarious and often 

 transversely rugose on the side ofthe stipule. S]>ikclets ."> to 7, rather clustered, 

 the uppermost one often almost entirely stand nate ; the others with each an ovate- 

 lanceolate bract at base, ending in a scabrous awn longer than the spikclet. 

 Stamina's glumes lanceolate, acuminate* Pistillate illumes ovate, long-mucron- 

 ate. Fruit compressed, concavo-convex, minutely serrulate on the margin, at 

 lenuth diverging, bifid at the apex. 



Hub. Hill sides: foot of Barren ridge: nut common. Fl. May. JV July. 



Obs. Resembles C. cep/talof>horu, in general appearance ; but the spikes are 

 more numerous, and not crowded into so compact a head. The fruit and glumes 

 also serve to distinguish it. 



6. C. stipata, JMuhL Spikeicts numerous, bracteatc, crowded into a 

 terminal, lance-oblong, compound spike ; bracts subulate, scabrous, 

 generally shorter than the spikelets ; fruit lanceolate, plano-convex, 

 nerved, spreading, nearly twice as long as the glume, the beak long and 

 tapering, serrulate on the margin. Beck, Hot. p. 432. Speciji,
