Juncus xiphioides is a species of rush known by the common name irisleaf rush. It is native to the southwestern United States and Baja California where it grows in wet areas in many habitat types. This is a rhizomatous perennial herb producing erect stems to a maximum height between about 40 and 80 centimeters. It has wide leaf blades for a rush, often exceeding one centimeter in width at the base. The few straw-colored leaves reach up to 40 centimeters in length. The large flower cluster has many clusters of up to 70 flowers each. The flower has very narrow green, red, or yellow-brown, lance-shaped petals and six stamens with very small anthers. The fruit is a brown oblong capsule.
