caryophyllales
Definition
Proper noun 1. A taxonomic order of flowering plants: Caryophyllales is a large and diverse order of dicotyledonous plants. It corresponds approximately to the older, now superseded, group Centrospermae. This order includes families characterized by features such as free-central or basal placentation and often betalain pigments (instead of anthocyanins in some families). Members range from carnivorous plants (like sundews) to cacti, beets, spinach, and many common ornamental flowers like carnations.
Usage Examples
- Proper noun:

- Botanists study the evolutionary relationships within Caryophyllales.

Advanced Usage
- Phylogenetic context: In modern botanical taxonomy, Caryophyllales is defined by molecular phylogenetic studies, which have clarified the relationships among its families and led to the inclusion of groups like the cacti.
