Differs from all other species (except E. eremophilus) by the
cartilaginous, glabrous palea of the basal floret. Also, the many-noded
strongly branched culms mostly covered by leaf sheaths are helpful features.
Main differences between the two species relate to dimensions, indumentum
and/or nervation of panicle, glumes, lemma and palea.
