Hippuris vulgaris
species of plant
Hippuris vulgaris (from Greek: ἵππος – horse and οὐρά – tail), known as mare's-tail or common mare's-tail, is a common aquatic flowering plant in the family Plantaginaceae. Its distribution ranges from Eurasia and North America to Greenland, the Tibetan Plateau and Arizona. It prefers non-acidic waters.
Description
The common mare's tail is a creeping, perennial herb, found in shallow waters and mud flats. It roots underwater, but most of its leaves are above the water surface. The leaves occur in whorls of 6–12; those above water are 0.5 to 2.5 cm long and up to 3 mm wide, whereas those under water are thinner and limper, and longer than those above water, especially in deeper streams. The stems are solid and unbranched but often curve, and can be up to 60 cm long. In shallow water they project 20–30 cm out of the water. It grows from stout rhizomes. The flowers are inconspicuous, and not all plants produce them.
This brief starts where responsible research should: with the source description of “Hippuris vulgaris” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q33115. 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.
How to read it
