Millettia Pinnata : Pongamia pinnata is one of the few nitrogen fixing trees (NFTS) to produce seeds containing oil. It is often planted as an ornamental and shade tree but now-a-days it is considered as an alternative source for Bio- Diesel. This species is commonly called pongam, karanja, or a derivation of these names. This oil is rapidly gaining popularity as an important source of fuel for diesel engines.
