the spikelet ; the nut is formed as usual in the 3rd glume, the rhacheola above its 

 base is exceedingly short, while the 4th glume (usually containing a barren' flower) 

 is well developed. — The ripe nut thus is contained apparently by the 3rd and 4th 

 glumes, notby the 3rd glume and the rhacheola.

 but from the structure of the spikelets it must be more closely allied to M. pictus.
