Definition

Noun: 1. A taxonomic order of flowering plants: In botanical classification, 'Aristolochiales' refers to an order of dicotyledonous plants. This order is characterized by a specific set of floral features, primarily a tubular, petal-like structure (perianth) and an ovary positioned below the attachment point of the other floral parts (inferior ovary).

Usage Examples

• Noun:
  • The botanical garden has a section dedicated to plants from the order Aristolochiales.
  • In older classification systems, the birthwort family was placed within Aristolochiales.
  • The defining characteristics of Aristolochiales include a perianth that is often petaloid and tubular.

Advanced Usage

• In Taxonomic Context: The term is used almost exclusively in scientific, botanical, and taxonomic writing. It is a formal, technical term for a group of related plant families.
  • The phylogenetic study suggested a re-evaluation of the families traditionally grouped under Aristolochiales.

Variants and Related Words

• Aristolochia (n): The type genus of the family Aristolochiaceae, which was the core family within the order Aristolochiales. It includes plants like Dutchman's pipe.
• Aristolochiaceae (n): The plant family encompassing birthworts and pipevines, which was the primary family in the order Aristolochiales.

Synonyms

• Birthwort order: A common name referencing the birthwort plant, a well-known member of this group. (Note: This is a descriptive synonym, not a formal taxonomic one.)

Important Note on Modern Classification

• The order Aristolochiales is a historical taxonomic grouping. In modern phylogenetic systems (like the APG system), the families once placed in this order have been redistributed. The core family, Aristolochiaceae, is now typically placed within the order Piperales. Therefore, the term Aristolochiales is primarily encountered in older botanical literature.

Noun

1. order of plants distinguished by tubular petaloid perianth and inferior ovary
