    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas; oblong; 3.5-4.5 mm long; as long as fertile; persistent. Companion sterile spikelet glumes chartaceous; distinctly veined; 7-9 -veined; dentate (3-4 teeth); truncate; muticous. Companion sterile spikelet lemmas 1-2; enclosed by glumes.
