Ammannia auriculata
species of plant

Ammannia auriculata, commonly known as eared redstem, is a species in the family Lythraceae that is found in tropical and subtropicalt areas around much of the world.
The slender and erect herb typically grows to a height of 5 to 40 centimetres (2 to 16 in). It blooms in March producing orange-purple flowers.
In Australia the species is found along the swampy margins of streams in a few scattered areas of the Kimberley and Pilbara regions of Western Australia extending into the Northern Territory and Queensland where it grows in black loamy soils.
In the United States it is found in Alabama, Arizona, Louisiana, Texas, South Dakota, Nebraska, New Mexico and Mississippi. It is found through much of Central America, Southern Chine and parts of Asia.
It is commonly found as a weed in rice paddies and on damp disturbed areas of soil.
Begin with the source’s own compact description: “Ammannia auriculata” is species of plant. The dossier treats that line as a proposition to test through Ammannia, auriculata and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Sep 28, 2025. The linked authority identifier is Q15244984. 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.
