Definition

Noun 1. A taxonomic order of flowering plants: "order Aristolochiales" refers to a specific botanical classification of dicotyledonous plants, historically recognized for having a tubular, petal-like perianth and an inferior ovary.

Usage Notes

• This term is primarily used in scientific, botanical, and taxonomic contexts.
• In modern classification systems (e.g., the Angiosperm Phylogeny Group system), the families within this order are often placed in other orders, such as Piperales. Therefore, "order Aristolochiales" is frequently encountered in historical or specialized botanical literature.

Examples

• Scientific Classification:
  • The plant family Aristolochiaceae was once placed in the order Aristolochiales.
  • Botanists studied the floral structure characteristic of the order Aristolochiales.

Advanced Usage

• In Taxonomic Hierarchy: The term is used to denote a rank above family and below class.
  • The defining features for order Aristolochiales included a sympetalous corolla and ovules attached to the ovary wall.

Variants and Related Words

• Aristolochiaceous (adjective): Relating to or belonging to the family Aristolochiaceae, which was the primary family within this order.
  • The aristolochiaceous vine displayed the tubular flowers typical of the old classification.

Synonyms
