Plant systematics investigates plant diversity and evolutionary relationships. Identification assigns a specimen to a taxon; nomenclature concerns names; classification organizes taxa. Keep these tasks distinct when reading a key or comparing a classification.

Study route

  1. Begin with the scope of systematics and its relationship to other biological sciences.
  2. Record diagnostic characters before proposing an identification.
  3. Compare classifications using the evidence and taxonomic framework stated by the source.

Check your understanding

Why can an organism’s accepted classification change while the specimen itself remains the same? Distinguish new evidence from a change in the organism.
