Here growing with Sea Arrowgrass. Marsh is the one with the long narrow fruits, the fruiting spikes being yellowish and more upright in this picture. Sea has more rounded fruits, and in this picture (but not in general) the spikes are at an angle. The two species often overlap around the high-tide mark. |
