American lyme grass is a common dune grass from Atlantic and Pacific coast beaches. Its bluish-green foliage and stout spikelets that contain more than one floret distinguish it from the common beach grass, Ammophila breviligulata, with which it often co-occurs. Dune grasses possess special adaptations that allow them to tolerate and grow faster in response to repeated burial by sand. As such, they are critical for stabilizing dunes against erosion.
