Prodr. 259 (1810) APNI
Tufted perennial with or without short rhizomes. Culms erect, new shoots occasionally arising from lower nodes, to c 90 cm high. Leaves cauline; blade hollow, with inconspicuous transverse septa when fresh, more obvious when dried, shorter or longer than the culms, slightly to distinctly compressed, c. 1–4 mm wide, apex acute or obtuse; auricles usually obtuse, up to c. 3.5 mm long. Inflorescence of (1–)2–75 close or distant clusters, each composed of 4–40 flowers, 7–14 mm wide in fruit; primary bract shorter or longer than the inflorescence; prophylls absent. Tepal midrib turning light brown, margins pale, membranous, reddish tinged towards apex; outer tepals (2.5–)3–4.7 mm long, acute to acuminate; inner equal to or longer than outer, acute to acuminate; stamens 6, anthers 0.4–1 mm long. Capsules light brown to golden-brown, trigonous-ovoid, 3–4.5 mm long, sub-equal to, or exceeding tepals by up to 1 mm, usually contracted rather abruptly (rarely tapering gradually) to an acute apex; seeds 0.5–0.6 mm long, slightly asymmetrical, finely reticulate-patterned discernible at moderately high magnification, minutely apiculate at each end. Joint-leaf Rush Flowers mostly Oct.–Dec., seeds shed mostly Dec.–Mar.

Closely resembles Juncus fockei and some intergrading may occur where the two species grow in close proximity. In addition to the key characters, J. holoschoenus tends to be taller and stouter in stature than J. fockei. Also resembles J. oxycarpus and J. acuminatus (see notes under those species).
