Triglochin concinna var. debilis

Slender arrow grass

Family: Juncaginaceae · Type: perennial · Native

Slender arrow grass is a California native perennial found in northeastern Klamath Ranges, northern California Ranges, southern Sierra Nevada, Great Basin, and Mojave Desert regions in alkaline meadows, seeps, mudflats, and along stream and lake margins at elevations of 400 to 2,500 meters. Flowering from March to August, this plant produces tiny green to white flowers in elongated inflorescences that typically extend well beyond its leaves. Growing to heights of 10 to 50 centimeters with slender, erect stems emerging from a fibrous base, it forms delicate, grass-like clusters in wet, saline environments. Its leaves are narrow, linear, and succulent, emerging from the base of the plant in a loose, spreading arrangement. The fruits are small, narrow capsules that develop along the elongated flower stalks, contributing to the plant's distinctive grasslike appearance.
