Botany pertains to the study of plants, which have always been of great importance since the formation of the planet 'Earth'. Plants play a crucial part in the life of living creatures as well as in balancing the environment. Apart from numerous benefits, obtained from plants, they have been a source of medication since immemorial times. Taking all these dimensions of plants into consideration, they have been classified into different groups and every one of them has been given a unique Botanical name. A plant may have different names in different dialects of different parts of the world, but its botanical name remains one and the same the world over. This multi-volume aims at furnishing a detailed account of plants from every possible dimension. A ready reference book for scholars and students, this encyclopaedia is an authoritative work on the subject.
