Root creeping, perennial. Culm 3 — 5 feet high, erect, or pro- 

 cumbcut at the base, generally simple, pubescent at the joints. 

 heaves a foot long, 2 — 3 lines wide, nervose, very scabrous 

 with minute hooked prickles, attenuated at the point ; margin 

 ciliate. Sheatha retroisely very scabrous. Sd/iule short, re- 

 tuse. Panicle much branched ; branches spreading in evtry 

 direction, sometimes pendulous, fltixuous, the lower ones 

 in fours, the upper ones in pairs. Flowera greenish- whitej 

 oval-oblong, nearly sessile, a little appressed lu the branches 

 When young, bui spreading when mature ; valves nearly equal, 

 scabrous oii the sides, puncticulate; the inferior 3-nerved, the 

 other 1 nerved; kecla ciliate with small spines. Stamens 3; 

 anthers linear, yellow. Styles 2, very short ; stigmas feathered, 

 white. Seed oblong. 



Hab. In ditches and swamps^ August — September. UhitC' 

 grass or Cut-grass. 



The upper flowers are generally abortive, those in the in- 

 cluded part of the panicle only being fertile. 



The two species here described have been confounded by 

 Michaux and Pursh^ though they are abundantly distinct. 

 I have not the means of determining whether our L. oryzoides 

 is identical with that of Europe, not having specimens of the 

 latter for comparison. It, however, much resembles the figure 

 of Stv art z referred to above.
