What is "pseudo-apuleius"

Pseudo-Apuleius is the name given to the author of a 4th-century herbal known as Pseudo-Apuleius Herbarius or Herbarium Apuleii Platonici. He is not identical with Apuleius of Madaura (124–170), the Roman poet and philosopher. Little or nothing else is known of Pseudo-Apuleius apart from this. The oldest surviving manuscript of the Herbarium is 6th-century Leiden, MS. Voss. Q.9. Until the 12th century it was the most influential herbal in Europe, with numerous extant copies surviving into the modern era. Thereafter it was more or less displaced by the Circa instans, a herbal produced at the school of Salerno. "Pseudo-Apuleius" is also used as a shorthand generic term to refer to the manuscripts and derived works.
