This species is recognized by the combination of broad leaf blades with hirsute sheaths and a glandular panicle of small spikelets.

The long filiform glume tips are readily broken off, so that the spikelets appear to be much shorter.

The key point is to break the disadvantageous correlation of filled grains percentage and spikelets per panicle.
