Oxybasis rubra
species of plant

Oxybasis rubra (until recently known as Chenopodium rubrum), red goosefoot, is an annual plant in the amaranth family. It is native to North America and Eurasia.
Description
Red goosefoot is a variable plant, an annual growing from just a few centimetres tall to as much as 1.5 m, usually erect but sometimes procumbent. It is sometimes quite fleshy plant, always glabrous, and usually green but sometimes red or, rarely, yellowish. The stems are ridged or angular and often branched, especially close to the base.
The leaves are alternate and roughly diamond-shaped, anything from 1 cm to 15 cm long, with a cuneate base and several lobes or large, blunt teeth. They can be quite succulent, especially in plants growing in brackish conditions. The petiole is about half as long as the basal leaves, shorter in the upper ones, and there is no stipule.
The inflorescence is essentially a spike with many dense glomerules, or ball-like clusters of flowers, interspersed with simple or leaf-like bracts. The flowers are of two types: the terminal ones being bisexual, with 4-5 perianth segments ("petals"), 4-5 stamens and 2 stigmas; the lateral ones are generally female with 3 perianth segments.

Why this record matters
“Oxybasis rubra” is worth following because a concise public description often conceals a longer documentary argument. Here, Oxybasis, rubra and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q17271894. 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.
