Impatiens, commonly known as Balsams or Jewelweeds belong to the family Balsaminaceae are annual and perennial herbs. The genus with more than 1000 species mainly distributed in Africa. North America, India, Sino-Himalayan region and SE Asia. The plants are mainly succulent, and with beautiful flowers, one of the prized horticultural valued plant. In India, the genus is represented with around 249 species out of which 177 species are endemic, with highest concentrations in two hotspots of India, i.e. Eastern Himalaya and Western ghats.

From the preface: The Himalayas, literally meaning as abode of snow , is a 2500 km long arc shaped mountain range which is not only jewelled with snow-clad peaks and glaciers, but also wide extended lush-green forests harbouring one of the most biodiversity rich regions on the earth. The entire Himalaya has also been included amongst 35 Global biodiversity Hotspots. The diverse ecosystems of Himalaya are not only not only present beautiful landscapes, but also play important role in global atmospheric circulation, the hydrological cycle, and water resources availability, and provide a wide range of ecosystem services to the local inhabitants. A comprehensive information on the plant diversity particularly on taxonomy, correct identity and distribution is need of the hour. The information is provided in two parts. All the families are arranged alphabetically. The part 1 deals from family Acanthaceae to Nymphaeaceae while the part 2 deals from family Nyssaceae to Zingiberaceae. The valid names are given in bold while the basionyms of synonyms were given in italics. The checklist divided into dicotyledons and monocotyleds, families within groups, genera within families and species and infra-specific taxa within genera are arranged alphabetically under each genus for the sake of convenience; in the end of the text a index to the family names is also included.
