We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Liriodendron — The entry states the Liberty Tree measured about 7.0 meters, but the correct circumference is 21.5 feet (6.6 meters); 7.0 meters is approximately 23 feet, which is inconsistent with the historical record.
Magnolia — The DID YOU KNOW section incorrectly states that Magnolia is the official flower of Seoul; Seoul's official flower is forsythia, not magnolia.
Magnoliids — The entry presents two conflicting dates for the split of magnoliids from other angiosperms (135 million years ago and 160–165 million years ago) without noting which is correct, and the widely accepted estimate is around 140–150 million years ago.
Magnoliids — The claim that 'Safrole from Sassafras or Ocotea cymbarum is the primary precursor for synthesis of MDMA' is incorrect because Ocotea cymbarum is not a standard source; the correct botanical source is typically Sassafras albidum or Ocotea pretiosa.
Nothofagus — The genus was first formally described in 1851 by Carl Ludwig Blume, but the correct year is actually 1850, not 1851.
Nothofagus — The statement that Nothofagaceae was introduced in 1960 by Ludmila Andreyevna Kuprianova is incorrect; the family was first proposed by H. G. A. Engler in 1897.
