angles. Spikelets more or less diverging from the rachis, 5- to 12- 
flowered, generally equalling 2 or even 3 internodes, ultimately elliptical 
or elliptical-wedgeshaped, much compressed. (jlumcs usually half 
the length of the spikelets, and only in few flowered s]:)ikclets reaching 
to three-quarters of their length, acute or awned or obtuse, with a keel
