 1797, not Linn. 1771.) Spikelets in pairs, partially embedded in the excavations 

 of the articulate rachis, one sessile and hermaphrodite, the other pedicellate, 

 the pedicel grown to the rachis. Glumes of the perfect spikelet awnless; the 

 outer empty one coriaceous, globose, pitted externally, and covering the cavity 

 in the rachis; the 2d equaling the 1st in length, less rigid, immersed in the cav- 

 ity of the rachis; the 3d empty, and, like the 4th, hyaline. Palea minute or 

 wanting; lodicules broadly wedge-shaped, truncate. Stamens 3. Styles dis-
