Common names: barb goatgrass, barbed goatgrass
Aegilops triuncialis (barb goatgrass) is an annual grass (family Poaceae) that grows in rangelands, grasslands, and oak woodlands. It is becoming a dominant grass in foothill grasslands of central California. This weed can directly injure livestock by lodging in their eyes or mouths, and is unpalatable to cattle.Cal-IPC Rating: High
