The plant grows to over {{convert|2|m|ft}} in height and is favoured in most environments by frequent burning. The plants develop characteristic dark seeds with a single long awn at one end and a sharp spike at the other. The awn becomes twisted when dry and straightens when moistened, and in combination with the spike is capable of drilling the seed into the soil.[1] The species is known as giant spear grass, and is closely related to the more common Black Spear Grass, with which it is commonly associated in Northern Australia.
