Juncus nevadensis var. nevadensis (Nevada or sierran rush) is a native California grass in the Juncaceae family, recognized by mountain meadow habitat with specific flower cluster arrangement.
Nevada or sierran rush is a California native perennial found in the Klamath Ranges, northern Coast Ranges, high Cascade Range, northern Sierra Nevada, Sierra Nevada, southern Coast Ranges, southern Transverse Ranges, and Great Basin in mountain meadows and streambanks at elevations of 1,200 to 3,300 meters. With limited flowering data, this rush displays dark brown perianth parts 3 to 3.8 millimeters long in clusters of 5 to 15 flowers. Growing 10 to 50 centimeters tall with distinctive leaf sheaths featuring noticeable crosswalls, it forms compact clusters in alpine and montane habitats. Its leaf sheaths have appendages 2 to 3.5 millimeters long, creating a characteristic dense growth pattern. The tiny seeds are narrow elliptic, measuring approximately 0.6 millimeters in length.
