Definition
Proper noun 1. A taxonomic order of plants: Juglandales is an order of flowering plants (dicotyledons) that is coextensive with, or essentially equivalent to, the walnut family, Juglandaceae. In some older or specific taxonomic systems, it is recognized as the order containing trees like walnuts, hickories, and pecans.
Usage Notes
- Scientific/Technical Term: This word is used almost exclusively in scientific contexts, particularly in botany, taxonomy, and paleobotany.
- Historical Usage: In many modern taxonomic classifications (e.g., the APG system), the order Juglandales is not recognized; its member plants are included within the larger order Fagales. Therefore, its use often refers to older classification schemes.
Examples
- The fossil record shows that the order Juglandales was widespread during the Tertiary period.
- In Cronquist's system of classification, Juglandales comprises the single family Juglandaceae.
Advanced Usage
- Phylogenetic Context: When discussing plant evolution, one might refer to "the former order Juglandales" to indicate its status in historical taxonomy versus current phylogenetic understanding.
Variants and Related Words
