Definition

Proper noun * Agavaceae: A family of flowering plants, primarily found in tropical and arid (xerophytic) regions. This family historically included groups like Dracaenaceae and encompasses plants sometimes classified under Amaryllidaceae or Liliaceae in other taxonomic systems. It is commonly known as the agave family.

Usage
  • The term Agavaceae is used in botanical taxonomy to categorize a specific group of monocot plants.
  • It is a formal, scientific name. In everyday language, people typically refer to member plants by their common names (e.g., agave, yucca) rather than the family name.
Examples
  • Botanists reclassified the century plant into the family Agavaceae.
  • Many plants in the Agavaceae, such as agaves, are well-adapted to dry climates.
  • The taxonomic boundaries of Agavaceae have been revised over time.
Advanced Usage
  • Taxonomic Revision: In modern phylogenetic classifications (e.g., the APG system), many plants once placed in Agavaceae are now often included in the expanded family Asparagaceae, under the subfamily Agavoideae. Therefore, Agavaceae may be used in a historical or specific taxonomic context.
Variants and Related Words
  • Agave (n): The type genus for the family, referring to the succulent plants commonly known as century plants or maguey.
  • Agavoideae (n): The subfamily name within Asparagaceae that corresponds to the traditional Agavaceae grouping.
  • Xerophytic (adj): A characteristic of plants adapted to dry environments, describing many members of this family.
Synonyms
  • Agave family: The common name for Agavaceae.
  • Subfamily Agavoideae: The modern phylogenetic equivalent in many classification systems.
