| Identification | Common Barnyard-grass is familiar to most naturalists. The stems grow mostly 2-4 feet tall and may be erect or reclining. The inflorescence is composed of a number of strongly ascending branches, each bearing many spikelets -- forming a conical shape. The spikelets are ovoid and rapidly taper to a short sharp beak; they usually bear awns, but some forms do not. Panicle branches usually have hairs abruptly widened at the base (pustular). In the field, the native E. muricata looks very similar but it has pustular hairs on the second glume and sterile lemma (vs. glabrous or glabrate). | |
| Taxonomic Comments | The specific name is often written as crus-galli.
