Path Rush (Juncus Tenuis) is a native perennial rush is typically 4-12"" tall.  It is often densely tufted with erect to ascending stems that are light to medium green, slender, glabrous, and unbranched. The leaves of each stem are basal or nearly so. The narrow leaf blades are about 1 mm. across and up to 10"" long; they are ascending or curve gently away from the stems. The leaf blades are medium green, glabrous, and flat to slightly involute (with margins that roll upward). The sheaths of young leaves are light green with membranous upper margins; later they become tan to brown and often somewhat shredded. At its apex, each sheath has a pair of soft membranous auricles (ear-like extensions) that are lanceolate in shape. Each fertile stem terminates in a branching inflorescence at its apex that is about ½–3"" across; this inflorescence has one or more umbel-like clusters of chaffy flowers. There are usually fewer than 10 flowers per cluster. At the base of this inflorescence, there are about 3 slender leafy bracts up to 4"" long that form a V-shape; the larger bracts extend beyond the inflorescence. Each flower has 3 scaly petals, 3 scaly petals, several stamens, and a superior ovary (later a seed capsule). The petals and sepals are nearly identical in appearance; they are about 3-5 mm. long and lanceolate in shape. Young petals and sepals are light green (sometimes with reddish tips), but they later become tan; as the flower matures, they spread slightly away from the ovary/capsule. At the base of each flower, there are tiny bractlets; they are ovate to lanceolate in shape.
