Barnyard Grass, Echinochloa muricata
Grasses at a Glance
Barnyard Grass, Echinochloa muricata, is a native summer annual found in every county in Illinois, typically in disturbed habitats or wetter areas. The leaves are rather broad, and this grass is unique because it does not have a ligule. Instead of a membrane or hairs you'll just see a horseshoe-shaped smooth raised surface.
This grass produces a panicle inflorescence with spikelets directly attached to the branches. The green to red spikelets are pear-shaped and covered in soft hairs. In this example, the spikelets are awned; however, you can find awnless varieties of this same species too.
