List of euasterid families
Remove ads

The euasterids or core asterids are a group of 69 interrelated families in 15 orders of flowering plants.[3][4][a] They tend to have petals that are fused with each other and with the bases of the stamens, and just one integument (covering) around the embryo sac.[3] The asterids as a whole (the euasterids plus two orders of basal asterids) represent almost a third of all flowering plant species.[8]

Thumb
Lamium album. Lamium originates from the Greek for "wide-open mouth" (on the flowers).[1][2]

The euasterids include trees, shrubs, vines and herbaceous perennials and annuals. Sweet potatoes are a tropical staple food. Basil, oregano, sage, rosemary, thyme and peppermint are all kitchen herbs in the mint family. Olives have been cultivated around the Mediterranean for food and oil for at least five thousand years. The daisy family includes lettuce, artichokes, Stevia, sunflowers and tarragon.[9]

Glossary

Perspective

From the glossary of botanical terms:

The APG IV system is the fourth in a series of plant taxonomies from the Angiosperm Phylogeny Group.[6] In this system, the euasterids are divided into the lamiids and the campanulids.[b] The order Icacinales is basal within the lamiids.[11]

Six euasterid orders have more than two families: Apiales, Aquifoliales, Asterales, Gentianales, Lamiales and Solanales. Apiales and Asterales are exceptionally diverse, with 2342 genera between them.[c] Aquifoliales is basal within the campanulids.[11] Gentianales species have pitted wood and opposite leaves that are joined across the stem. In Lamiales, plants are mostly herbaceous with opposite leaves, and the five-lobed flowers have approximate mirror-image symmetry. Solanales species usually have sepals that continue to grow with age, even when the plant is fruiting.[12]

Notes

  1. The taxonomy (classification) in this list follows Plants of the World (2017)[5] and the fourth Angiosperm Phylogeny Group system.[6] Total counts of genera for each family come from Plants of the World Online (POWO).[7] (See the POWO license.) Extinct taxa are not included.
  2. There have been signs of support since APG IV for one or more new euasterid orders that belong to neither the lamiids nor the campanulids.[11]
  3. See the table for totals.
  4. Each family's formal name ends in the Latin suffix -aceae and is derived from the name of a genus that is or once was part of the family.[13]
  5. Some plants were named for naturalists (unless otherwise noted).
  6. Many taxonomists prefer to place Calceolaria and Jovellana into a separate family, called Calceolariaceae.[6][139][140]
