This plant is characterized by its tall, tufted annual growth with coarse stalks. Its stems typically sprawl along the ground before ascending upwards. The elongated leaves are flat, smooth, and slightly rough along the edges, with a prominent light-colored mid-vein. Ligules are absent, and blade sheaths are smooth, sometimes displaying a reddish hue closer to the ground. The panicle is dense, green or purple, and protrudes slightly, with branches that may droop.
