Many grass species are difficult for the uninitiated to identify to species. This one is an exception because of the unique geometry of the inflorescence. Typically there are four orthogonal rachises branch from the top of the central rachis. Examples with more radiating rachises, are also to be found. Sharp bristles on the spikes likely deter grazers.
