Caryophyllidae is a subclass of plants in the older Cronquist classification scheme. In more modern schemes, the two orders Polygonales and Plumbaginales are classified as families within the order Caryophyllales, and the subclass Caryophyllidae is no longer recognized. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...
