Family: Juncaceae · Type: perennial · Not Native

Bolivian rush is a naturalized perennial herb found in northern Sierra Nevada mountains in Butte and Yuba counties, occurring on creekbanks, damp meadows, and yellow-pine forest areas at elevations of 600 to 1,100 meters. This grass-like plant has leafy stems with conspicuous nodes, growing 5 to 50 centimeters tall with a long, nearly erect rhizome. Growing with spreading branches and multiple clusters, the plant produces green perianth parts 2.2 to 3.9 millimeters long with six stamens. Its leaves are evenly spaced along the stem, 4 to 20 centimeters long and 2 to 8.5 millimeters wide, with a flat side oriented toward the stem. The fruit extends beyond the perianth, gradually tapering to a small beak 0.5 to 1 millimeter long.
