Fl. Bor.-Amer. 1: 192 (1803) APNI
Tufted, sometimes shortly rhizomatous perennial. Culms erect, 30–85 cm high. Leaves cauline and basal; blade hollow, with ± conspicuous transverse septa, very rarely exceeding the culms, compressed or terete, c. 1–3 mm wide, apex acute or obtuse; auricles usually obtuse, to c. 3 mm long. Inflorescence of 5–70(–100) usually discrete clusters, each with 4–20 (rarely more) flowers, 5–8 mm wide in fruit; primary bract shorter than inflorescence; prophylls absent. Tepal midrib green, turning light brown, margins pale, membranous, the ± curved tips often tinged reddish-brown; outer tepals (2.5–)2.8–3.5 mm long, acuminate; inner shorter or sub-equal to outer, acuminate. Stamens 3, anthers 0.5–0.7 mm long. Capsules light brown to red-brown, slightly 3-angled in the upper half at maturity, narrowly ovoid, c. 2.5–3.5 mm long, shorter than or subequal to tepals, tapering to a broadly acute and shortly mucronate tip; seeds c. 0.3–0.4 mm long, slightly asymmetrical, very fine longitudinal and transverse ridges discernible at moderately high magnification, minutely apiculate at each end. Flowers recorded Jan., fruiting period unknown.
*EGU, *GipP, *HNF, *MuM, *NIS, *VRiv. Also naturalised in NSW, Tas. Native to North and South America. Naturalised in New Zealand. Known in Victoria from a few recent (1980-2011) collections in the Walwa, Tubbut, Lake Nagambie, and Tonimbuk areas.
Similar to Juncus holoschoenus, but differs in its smaller seeds, fewer stamens and generally smaller fruit clusters.
