Inflorescence with flowers aggregated into few to many subglobular clusters, the clusters close or distant; primary bract continuous with culm, to c. 25 cm long; prophylls present. Tepals often with a faint reddish-brown longitudinal band on either side of the green (later turning stramineous) midrib, 2.6–3.8 mm long; stamens 6 (rarely 3), anthers 0.6–1.0 mm long. Capsules stramineous with a slightly darker apex, shorter than or equal to the tepals, 2.0–3.0 mm long; dehisced capsules with minute reddish flecks on the inner surface.

Resembles Juncus phaeanthus (see key) and J. australis: from the latter, it is distinguished by the cobwebby continuous pith, the paler cataphyll bases, the superficial stomates and the minute reddish flecks on the inner walls of open capsules. Hybrids with J. continuus are known.
