The Heteropogon contortus is a plant of the order Poales, commonly known as the Black Speargrass, Tanglehead and Pili. It can be characterised by the twisted awn at the topmost part of the plant when the seeds have developed.
It is a tropical, perrenial tussock grass that is distributed across North Australia, parts of Africa and Asia. It grows to 1.5 metres tall.
It is a native weed to Australia and problems exist where the seeds can cause discomfort for sheep.
