According to Almond 1993, the Botanic Garden is an ever changing museum of living plants. Chakravarthy and Mukhopadhyay 1990 described Btoanic Garden as a living repository or refugia of plants arranged and maintained on some scientific basis and where the collections are usually labeled or marked for identification. Heywood 1983 of the view that the Botanic Gardens and arboretum are at best represent the last resort for the preservation and maintenance of rare and endangered species.

From the Introduction: A botanic garden can be called as an open museum of living collection of myriad of plants, where trees, shrubs, herbs, climbers, lianas etc. are scientifically arranged, properly labelled based on an internationally accepted classification, and more closely allied groups/plants are specially grown together for better understanding of species. Here in botanic garden trees are confined to a special section called arboretum: gymnosperms including pine trees are arranged in pinetum, screwpines i.e. pandanus are grown in Pandanetum, Orchids are assembled in Orchidarium,Bamboos are nurtured in Bambusetum and Palms are conserved in Palmetum.
