Vegetative identification: There is a tuft of hair at each edge of the collar plus hairs extending down the outer margin of the sheath. Blades are bright almost lime green, with a prominent mid-rib on the back of the blade and prominent veins on top of the leaves. The leaves are very rough on the upper surface and to a lesser extent on the bottom. Blades are rolled at emergence and seedlings often have a twist at the end of the blade.
