Setaria parviflora is a species of grass known by the common names marsh bristlegrass,[2] knotroot bristle-grass,[3] bristly foxtail and yellow bristlegrass. It is native to North America, including Mexico and the United States from California to the East Coast, Central America and the West Indies,[4] and South America.[5]

This grass is a perennial with small, knotty rhizomes. It produces stems 30 centimeters to well over one meter tall. The leaf blades are up to 25 centimeters long and under a centimeter wide.[4] The leaves are whitish-green.[6] The inflorescence is a compact, spikelike panicle up to 8 or 10 centimeters long. Surrounding each spikelet are up to 12 yellow or purple bristles.[4] The bristles stay on the stalk after the seeds drop away.[6]

This grass grows in moist habitat.[4] It can grow in salty habitat such as salt marshes.[6]
