Q. Describe Bentham and Hookers System?
Bernard de Jussieu (1699-1776) tried to classify the plants in Royal Garden, Paris. During this exercise he developed a system of classification which is, in fact, the first natural system of classification. Soon after, A.P, de Candole (1778-1841) proposed a system of classification which was nothing but the modified form of de Jussieu's system.
Based on the general principle of Form-relationships, the most popular of the natural systems of classifications-was proposed by two British Botanists George Bentham c1800-1884) and Sir Joseph Dalton Hooker (1817-1911). Hooker being the Director of Royal Botanic Gardens, Kew, had all the facilities at his disposal. Bentham and Hooker published the monumental work "Genera Plantarum" (1862-1883). This work includes names, accurate description and classification of all the seed plants
known at the time (nearly 97,205 species). The term family was designated as order and the term "Order" was named as. Cohort. This system of classification is adopted in most of the common wealth countries including our country. In all 202 families were recognised in this system. The starting family being Ranunculaceae and Poaceae as the ending family.
