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, not by the 3rd glume and the rhacheola.

(mostly 2) nuts.—From the stolons this plant is usually mixed with M. pameus, 
but from the structure of the spikelets it must be more closely allied to M. pictus.
