faintly ribbed green much exceeding the oblong-ovate glumes, beak flat- 

 tened 2-cuspidate scabiid.

49. C. Iseviga'ta, Sm.; tall, leaves short broad, spikelets distant 

 pedicelled inclined or drooping cylindric, perigyuia subsessile elliptic-

 hardly 3-gonous perigynia, ribbed at the 2 obscure angles only, and the
