Nabalus
genus of plants
Nabalus is a genus of Asian and North American flowering plants in the tribe Cichorieae within the family Asteraceae.
Nabalus is now considered the correct name for a group of plants in North America that were formerly considered to be members of Prenanthes, and were included in that genus in the Flora of North America treatment. Common names for the genus include "rattlesnake root" and "white lettuce." The latter reflects its close relationship to lettuce (Lactuca sativa) but having flowers that are whitish or purplish-white in some species. Many (perhaps all) of the species are monocarpic perennials, in which an individual plant may live for multiple years in a vegetative condition but then will die after flowering and fruiting.

Begin with the source’s own compact description: “Nabalus” is genus of plants. The dossier treats that line as a proposition to test through Nabalus, 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 Sep 18, 2026. The linked authority identifier is Q5487724. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026, 1871, 1923 and 1833.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
