Usage Notes

• This term is primarily used in the context of scientific botany, taxonomy, and plant biology.
• Its taxonomic scope has been revised in modern classification systems (like APG). It is often considered synonymous with or subsumed within the order Lamiales.
• It is typically used in its full form "order Polemoniales" or simply "Polemoniales".

Examples

• The order Polemoniales traditionally encompassed families like the mint family (Lamiaceae) and the nightshade family (Solanaceae).
• In older classification schemes, plants with fused petals and superior ovaries were often placed in the Polemoniales.
• The phylogenetic study suggested reclassifying several families out of the Polemoniales.

Advanced Usage

• In taxonomic hierarchy: The term is used to denote a rank above "family" and below "class".
  • The family Polemoniaceae is placed within the order Polemoniales.

Variants and Related Words
