Spikelets l-llo\vcred. flat, articulate on short ])c'di('ols along the 

 slender branches of a terminal panicle. Glumes 2. cninjilicate and 

 keeled, the outer the larger, surrounded at the base by a carti- 

 laginous ring, which is often obscure; outer glume 5-ncrved, 

 broadly wing-keeled or with tlie margins ciliate, the inner 3-nerved. 

 No 2-nerved palea. Stamens G, 3, or fewer. Styles short, dis- 

 tinct, (xrain enclosed in the slightly hardened glumes, but not 

 adherent. 



Marsh grasses, with narrow leaf-blades which quickly close when 

 warm, if briskly nibbed. The main nerve one side of tlie middle 

 of the blade. Panicle terminal, slender, with erect filiform rays. 

 Spikelets smaller, more slender, and neai*er together than in Ovyza, 

 and in //. lenticnlaris almost imbricate. Nerves of the glumes 

 not very prominent. 



Six or more species, five at least common to America. Nearly 

 allied to Orj/za, though having thinner glumes, a different inflo- 

 rescence, and no small outer glumes. 



The old and long-used name Lccrsia was first used to designate 

 a genus of mosses, and therefore should not be used for any other 

 jilant.
