Definition
- Proper noun (Taxonomy):
- An order of coniferous plants: Taxales is an order of gymnosperm plants within the division Pinophyta (conifers). It is characterized by its members, which are typically evergreen trees or shrubs.
- Coextensive with the family Taxaceae: In some modern taxonomic classifications, the order Taxales is considered to contain primarily (or solely) the yew family, Taxaceae. This reflects a close historical association between the order and this specific family of plants.
Usage Notes
- The term "Taxales" is used almost exclusively in scientific, botanical, and taxonomic contexts. It is not used in everyday conversation.
- Its usage may vary depending on the specific taxonomic system being referenced, as plant classification is periodically revised.
Examples
- Scientific Context:
- The order Taxales includes several genera known for their toxic seeds and arils.
- In older classifications, Taxales was distinguished from other conifer orders by its solitary seeds not borne in cones.
Advanced Usage
- Taxonomic Revision: In contemporary phylogenetic systems (e.g., the Angiosperm Phylogeny Group system), the traditional order Taxales is often not recognized. Instead, the family Taxaceae is frequently placed within the order Pinales. Therefore, stating "the order Taxales" often implies a reference to a specific, sometimes older, taxonomic framework.
- The family Taxaceae was formerly placed in its own order, Taxales.
Variants and Related Words
- Taxaceae (n): The yew family; the primary family within the order Taxales.

- Taxus (n): The genus of yews, a key genus within the family Taxaceae (and thus historically within Taxales).

Synonyms
