The rich floristic diversity of the state of Sikkim has attracted the plant - explorers from different parts of the world since remote epoch. But till to day the Flora of Sikkim could not be published. Sikkim is regarded as a store house of many wild relatives of economic plants, which are of immense value to the man kind.
