An electronic pollen flora including digital and scanning electron micrographs and descriptions distinguishes itself by the graphic identification system of pollen without the plethora of terms; it enables many levels of users (in South India as well as in the tropics, subtropics and sub-temperate regions in India, Asia and other continents) to learn palynology by the "click of the mouse". The descriptive part furnishes palynological terms linked to the illustrated definitions and the bibliographic link for quick reference. Pollen Typification; and Taxonomical, Ecological and Distributional notes for the selected 147 genera (Mangroves: 11, Western Ghats: 129 and others: 7) are also given.
A microtaxonomic, research tool, (adapted from IDAO by CIRAD) will aid "users" interested in climate related past vegetational changes.
