Jharkhand CECEJharkhand CECE 2005

Solution:

Pbylogenetic system involves the classification of plants, .according to the evolutionary and genetic affinities. This system of classification was proposed by Engler in $1886$, by Hutchinson in $1926$ and by Tippo in $1942$. John Hutchinson $(1884-1972)$ ah English botanist has given the latest information about the phylogenetic classification of angiosperms which has been published in his famous work Families of flowering plants recently in $1959$ (after being published twice in $1926$ and $1934$). Carolus Linnaeus $(1707-1778)$, a great Swedish botanist known as Father of Modern botany followed the binomial system of nomenclature. He proposed an artificial sexual system of classification containing $24$ classes. The outline of the classes of his system was published in Systema Naturae in $1735$, and again in Genera Plantarum in $1737$. George Bentham and Sir Joseph Dalton Hooker, established and published jointly a Natural System of Classification, containing $202$ orders, in a monumental work Genera Plantarum. It is the most popular, and applicable system. Theophrastus $(370-285 B.C)$, the Father of botany classified plants on the basis of form and texture. He has described about $450$ cultivated plants and classified them in his Historia Plantarum. His classification was strictly artificial.
