The biodiversity of Sikkim has always been held in high admiration in the scientific community, especially that of flowering plants, with explorers being enthralled by the vibrant array of mesmerising plant diversity of Sikkim. Nevertheless, a comprehensive account of all the flowering plants of Sikkim in a single compendium was elusive and its need was acutely felt in these times of rapid climate change. Botanical Survey of India has data of flowering plants of Sikkim stretching almost two centuries. This book, “Flora of Sikkim - A Pictorial Guide” gives up-to-date data available with BSI and other published records on the flowering plants of Sikkim.
