deer tongue grass, close up, md, upper marlboro

Green seed of one of my favorite grasses, I leave patches of this plant when I mow the "lawn." Presumably this is Dichanthelium clandestinum (formerly Panicum clandestinum), but am not sure if there are look alikes in my area.Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200, link to a .pdf of our set up is located in our profile
