Conservation status: CNPS 2B.2

Inland rush is a rare (CNPS 2B.2) California native perennial found in the San Bernardino Mountains in granitic washes at elevations of 1,800 to 1,900 meters. Flowering in summer months, this rush produces small green to pale brown flowers in clustered, slightly open inflorescences. Growing in dense tufts 11 to 60 centimeters tall with upright stems, it forms compact clumps in rocky mountain habitats. Its leaves are narrow, flat, and 0.5 to 1.1 millimeters wide, with membranous sheaths and minimal leaf appendages. The plant produces small ellipsoid fruits that are typically longer than its perianth, with minute, blunt seed appendages.
