Juncus holoschoenus

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.
