Q. What do you mean by Transition Period?
The transition period from the Renaissance to the Modern period produced many notable workers and much literature. Botanists gradually broke away from the traditional doctrines of the ancients and developed new systems of classification, a new terminology of description, and a system of nomenclature that was to become a permanent part of taxonomy. Since the concept of evolution, had not yet been developed, the arrangement of plant groups in various system of classification was still more artificial than phylogenetic.
