Plant Family Name Changes: Official Botanical Names and Legacy Terms

Accurately identifying plants requires familiarity with their family names, which have evolved for standardization—much like surnames passed down through generations in botany.

Here are the key families with updated names (official modern name first, followed by traditional terms still appearing in older references):

  • Apiaceae = Umbelliferae
  • Asteraceae = Compositae
  • Araceae = Palmaceae
  • Poaceae = Grasses
  • Fabaceae = Legumes, Mimosaceae, Caesalpiniaceae, Papilionaceae
  • Brassicaceae = Crucifers
  • Lamiaceae = Labiaceae

These shifts ensure consistent global nomenclature, rooted in a representative genus for each family: Asteraceae derives from Aster, Lamiaceae from Lamium, while the former Labiaceae referenced Labia, meaning lips.
