Sjjikelets in pairs in the alternate notches of the articulate or 

 almost entire rachis of a simple spike, the first sessile and embedded 

 in a cavity of the rachis, with one perfect flower and sometimes a 

 staminate one below it, the other on a closely appressed or aduate 

 pedicel, but often spreading with a staminate or rarely a perfect 

 flower, or reduced to 1-2 empty glumes. The spike single on each 

 peduncle above a sheathing bract and cylindrical or nearly so. 

 Glumes in the sessile spikelet 4, the outer one coriaceous, flat- 

 tened on the back, closely covering the cavity of the rachis, second 

 thinner but often firm, concave or keeled, third and fourth and 

 the palea hyaline, all awnless. Stamens 3. Styles distinct. 

 Grain enclosed, but not adherent. 



In addition to the above from Bentham, our 4 species are 

 smooth, tall perennials, blades compressed and pointed. The 

 second glume of the sessile S2:)ikelets ovate, acute, compressed, 

 keeled, 3-nerved, third and fourth glumes and the palea ovate.
