Source-derived summary

Juncus uncialis is a species of rush known by the common names twelfth rush and inch-high rush. It is native to the western United States, where it is known from wet habitat such as vernal pools. This is a petite annual herb forming dense clumps of hair-thin green stems no more than 3 or 4 centimeters (1.2 or 1.6 in) high. The inflorescence is made up of a single tiny flower atop each stem. The flower has several reddish segments about 2 to 5 millimeters long wrapped around the developing fruit.

Editorial summary

The public source identifies “Juncus uncialis” as species of plant. This brief keeps that definition visible, then builds a research path around Juncus, uncialis and species.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 91-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Juncus, uncialis and species providing the first useful test.
Editorial analysis

Why this record matters

Critical limits

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.
