What is spear-grass?

Spear-grass is a common name given to several species of grass that bear sharp-pointed seeds or spikelets. These plants belong to the genus Aristida and are found in many parts of the world, including North and South America, Africa, and Asia.

Spear-grasses are typically drought-resistant and grow in various types of soil, including sandy, gravelly, and rocky substrates. They typically have long, thin leaves that grow from the base of the plant and produce upright stems that bear clusters of spikelets.

The spikelets of spear-grasses vary in size, shape, and color, depending on the species. They are typically covered in sharp, needle-like awns, which allow the seed to attach to passing animals or be blown by the wind. Some species of spear-grass are important forage for wildlife, while others are considered weeds that reduce the productivity of agricultural land.

Spear-grasses have been used for various medicinal purposes by indigenous people, such as treating wounds and fever. Additionally, some species are also used as a source of fiber for weaving baskets, mats, and other materials.
