The auricles are found (if present) at the base of the leaf blade, where the blade attaches to the main stem. They are appendages which when fully formed give the appearance of "finger" enclosing the stem. They may be long and claw like, short or rudimentary, or may be absent all together. While long claw like auricles are not found on many grasses they are very easy to spot on grasses which do have them like Annual Ryegrass (Lolium multiflorum).
