Juncus parryi (Parry's rush) is a native California grass in the Juncaceae family, recognized by high elevation dry habitat with very few flowers.
Parry's rush is a California native perennial found in the Klamath Ranges, northern California mountains, Sierra Nevada, San Bernardino Mountains, and White and Inyo Mountains in dry sunny slopes at elevations of 2,000 to 3,800 meters. With limited flowering time details, the plant produces pale brown flowers with delicate perianth parts 5 to 7 millimeters long. Growing as a densely clustered herb 6 to 30 centimeters tall with stem-like blades 3 to 8 centimeters long, it forms compact tufts. Its basal leaves feature multiple sheaths with minimal or obscure appendages, with leaves emerging only on the distal stems. The plant produces distinctive 3-angled fruits slightly longer than its perianth, with seeds 1.1 to 2 millimeters long featuring small 0.4 to 0.7 millimeter appendages.
