5^2 Description of some Gramineous Plants . [Sept. 



Folia in esemplaribus spontaneis semper emersa et erecta*, lanceo- 

 lata, basi cordata, obtusa, apice sub-cucullata, rigida, supra tactu 

 scabra. 



Panicula erecta, axi ad ejus originem subito angustata ; rami infimi 

 subverticillati, divaricati, superiores alternantes, ascendentes. 



Spicule rctmis adpressae, subsecundae, inferiores geminatae, inaequa- 

 liter pedicellatae, superiores solitariae longius pedicellate. 



Pedicelli clavati, infra medium constricti, ibidemque annulo rubro 

 insigniti, spicularum infimarum curvati. 



Paleae sessiles, apicum pedicellorum continuae ! vix compress* ; 

 exterior major 5-venia, venis denticulato-ciliatis, caeterum parce hirta ; 

 arista continua, recta, scabra, paleam excedens ; interior mutica, acu- 

 minata, 3-venia, carina denticulato-scabra, venis lateralibus laevibus, 

 pallidis. 



Lodiculae 2, subacinaciformes, magnae, extrorsum gibbosse et car- 

 nosae, introrsum sub-membranaceae, glabrae vel apice ciliatae. 



Stamina 6. Filamenta longe exserta. Antherae lineares, longae. 

 Ovarium oblongum, glabrum. 

 Stigmata ratione stylorum longiuscula. 

 Caryopsis non visa ; stipitata ? 



It is tins genus that appears to me allied to Zizania. It differs, 

 I conceive, materially from the preceding in habit, in the shape and 

 consistence of the paleae, which are open during the period of inflo- 

 rescence, and in the outer one being awned.
