Juncus mertensianus
species of plant
Juncus mertensianus is a species of rush known by the common name Mertens' rush or Alaska rush. It is native to much of western North America from Alaska to Saskatchewan to New Mexico, where it grows in wet mountainous areas such as riverbanks and alpine meadows. This is a clumping perennial herb growing from a vertical rhizome. Its smooth, flat stems grow to a maximum height near 40 centimeters. Its few leaves are located at the base and also along the stem. The inflorescence is made up of usually one cluster of many flowers. Each flower has shiny dark brown to black tepals 3 to 4 millimeters long, six stamens with yellowish anthers, and long reddish stigmas, as in image at left. The fruit is a dark, oblong capsule, as in image at right.

Why this record matters
“Juncus mertensianus” is worth following because a concise public description often conceals a longer documentary argument. Here, Juncus, mertensianus and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Feb 19, 2026. The linked authority identifier is Q6311875. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
