Suffix

[edit]

-aceae f pl

  1. (taxonomy) Used to form the name of taxonomic families of plants, algae, bacteria, and fungi

Usage notes

[edit]
  • A family name is formed from the name of a genus that belongs to the family by substitution of the ending of the genitive singular form with "-aceae".
  • There are only eight exceptions to the rule of using the -aceae termination for taxonomic families under the International Code of Nomenclature for algae, fungi, and plants (Melbourne Code, 2011), for a few widely used names that pre-date the rule. Each also has an accepted alternative (nomen alternativum), given in brackets:
  • In English, family names ending in -aceae are usually treated as plural (e.g., "Cunoniaceae are" or "the Cunoniaceae family is").
  • In English, most family names ending in -aceae follow the pronunciation patterns of /ˈeɪsi, -siˌaɪ, -siˌeɪ, -siˌi/) (e.g., Solanaceae, /ˌsoʊləˈneɪsi/).
