Usage notes

Depending on context, when used to mean the classification of biological organisms, this may be the same as taxonomy or distinct. When distinct, systematics can mean the research into the relationships of organisms (phylogenetics), while taxonomy involves itself in the recognition and the naming of taxa. Alternatively, Systematics can mean the broader category that includes both phylogenetics and taxonomy.
