Juncus inflexus
species of plant

Juncus inflexus, the hard rush, is a species of flowering plant in the family Juncaceae, native to Europe, Asia and Africa, and introduced in Sri Lanka, Java, Île Amsterdam and Île Saint-Paul, Victoria in Australia, New Zealand, Uruguay, and eastern North America. It is a glycophyte (non-halophyte).
Description
J. inflexus is a rhizomatous tufted perennial usually growing 0.5 – 1m tall. The stiff, glaucous stems are thin and wiry, measuring 1 – 2.5 mm in diameter. They are lined with 15 – 20 distinct vertical ridges and filled with interrupted spongy pith. Stomata are arranged along the stem in 5 – 10 rows.
The basal sheaths are a shiny reddish black.
It blooms from late spring until midsummer, producing loose clusters of very small reddish-brown flowers at the top of some stems. These later ripen into brown short-beaked seed capsules.

Why this record matters
“Juncus inflexus” is worth following because a concise public description often conceals a longer documentary argument. Here, Juncus, inflexus and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Mar 2, 2026. The linked authority identifier is Q161332. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
