Appearance

This is an annual grass with decumbent or erect stems growing up to a meter long. The leaf blades are up to 25 centimeters long and have a long sheath around the stem. The inflorescence is a dense panicle up to 15 centimeters long which tapers at both ends. It contains many small spikelets and bristles. The bristles have tiny backwards-pointing barbs that help them hook onto clothing or animal fur, facilitating their dispersal.

Seeds of the grass are used to make beer in South Africa and porridge in Namibia. They have been used as a famine food in India.
