The British naturalist, J. D. Hooker published seven volumes on Indian botany, with information from diverse parts of India for agricultural, horticultural and medicinal purposes. Along with this elevation map, it was one of the most complete surveys of Indian botany to date. In his words, India is “what is perhaps the richest and is most certainly the most varied botanical area of the surface of the globe.” The volumes served as guides for the study of economic and horticultural botany throughout the world.
