Question: Describe bentham and hooker system of classification?

The Bentham and Hooker system of classification is a method developed by George Bentham and Joseph Dalton Hooker for classifying seed-producing plants. Published in the three-volume work "Genera Plantarum" between 1862 and 1883, this system categorized an estimated 97,205 species into 202 families and 7,569 genera. It is considered a natural system because it is based on the observable characteristics of plants, such as the type of perianth, the number of whorls, and whether the whorls are fused or free. The system divides phanerogams into three classes: Dicotyledonae, Gymnospermae, and Monocotyledonae, with further subdivisions within these classes based on the structure of the flowers and other plant parts. Despite its extensive use, the Bentham and Hooker system does not account for evolutionary relationships, as it was developed before the widespread acceptance of Darwin's theory of evolution. Consequently, it is not a phylogenetic system. Nevertheless, it has been influential in the field of botany and is still used for reference and educational purposes, particularly in regions like India and the United Kingdom.
