They are valued by the Indians for their esteem, culture and welfare. Select 20 exotic  notable species are studied from the standpoint of their origin, distribution, culture and ancient Sanskrit literature. Diverse information about them is adduced from architecture, art, archaeological sites, etymology (philology), anthropology,  ancient Sanskrit and religious scriptures. Some of them were once thought introduced by western rulers in the then India few centuries ago. This belief can be easily negated based on the present investigation.
