The history of plant classification begins with the recognition of different species and types by natural historians, who drew and arranged them in basic divisions. The development of new classification schemes and a deeper understanding of evolution eventually led to a more holistic approach. The professionalization of botany in the 18th and 19th centuries also played a role in the shift toward non-anthropocentric classification methods. During the Victorian era, there was an increase in plant hunting and the Linnaean system of classification was widely used. Horticulture also played a role in modernizing agricultural practices. Carolus Linnaeus' 1756 compendium, Species Plantarum, remains a popular classification method. The work of famed botanist Joseph Dalton Hooker, who went on numerous expeditions and wrote foundational works on plant classification, also made significant contributions to the field.
