To identify with it when we talk about the family of plants, which tend to change sometimes... Like these young ladies who marry and then bear the name of their husband!
The main families having changed names are the following (first, it is the new official name, second, the name still sometimes used and present in the books which date a little)
If the surnames have changed, it is to standardize the denomination. Each family has a representative whose name serves as a root:Asteraceae comes from aster, Lamiaceae comes from Lamium, and formerly Labiaceae came from Labia meaning lips.
