plant-identification
Plant identification is the scientific process of matching a plant specimen to a known species or taxon using taxonomic expertise, identification keys, or modern computational tools. Accurate identification is foundational to plant science, enabling researchers to correctly attribute ecological, biochemical, and physiological observations to specific species. Advances in image recognition and molecular techniques are expanding identification capabilities beyond specialist taxonomists, accelerating biodiversity documentation and applied research.
