Taxonomy
The taxonomic history of the genus name Rhaponticum is complicated. It has been published at least four times according to the International Plant Names Index. The earliest was by Albrecht von Haller in 1742, which is regarded as an invalid name (nom. inval.). The next publication was by Sébastien Vaillant in 1754, also an invalid name. The next was by Christian Gottlieb Ludwig in 1757. This has become a conserved name (nom. cons.), with the conserved type species Centaurea rhapontica (syn.
Begin with the source’s own compact description: “Rhaponticum” is genus of plants. The dossier treats that line as a proposition to test through Rhaponticum, genus and plants, not as a finished interpretation.
Why this record matters
The phrase “genus of plants” 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 Jul 31, 2026. The linked authority identifier is Q2703875. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2023, 1742, 1754 and 1757.
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.
