This brief starts where responsible research should: with the source description of “Nicotiana” as genus of plants. 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 genus of plants. Its deeper value depends on whether names, dates, institutions and citations support that framing.
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 Q851829. The Library of Congress control number is sh85091816. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
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.
How to read it
