Plant identification Plant identification Plant identification is the process of matching a specimen plant to a known taxon. It uses various methods, most commonly dichotomous keys or multi-access keys. Plant identification has evolved over hundreds of years and depends to a large extent on what criteria and whose system is used. Plant identification implies comparisons of certain characteristics and then assigning a particular plant to a known taxonomic group, ultimately arriving at a species or infraspecific name. In the history of botany many large systems, useful at the time, were widely used for decades until superseded as taxonomic knowledge progressed. The study
