Juncus macrandrus

Long-anthered rush

Family: Juncaceae · Type: perennial · Native

Long-anthered rush is a California native perennial found in the Sierra Nevada Mountains, Transverse Ranges, San Jacinto Mountains, and eastern Sierra Nevada in wet meadows, creekbanks, and conifer forest at elevations of 1,200 to 2,900 meters. Flowering from June to September (inferred), this plant produces dark purple-brown flowers with occasional green midveins. Growing in dense clusters with creeping rhizomes, it forms tufted stems 30 to 50 centimeters tall with flat leaves 1.5 to 3.5 millimeters wide. Its basal leaves have overlapping bases with edges oriented toward the stem, creating a distinctive growth pattern. The fruit is characterized by a widely oblong body shorter than the perianth, with seeds that are narrowly elliptic and delicately net-veined.
