Assuming the importance of Papilionaceous plants in improving the habitat conditions in the highly degraded vegetations attempt has been made to record such plants growing naturally ill semiarid and chiefly red-lateritic soils of Sambalpur District of Orissa. As much as 62 such species has been recored growing naturally in this tract. The phenology of the plants along with its nodulation has also been collected. Introduction of these plants in the plantation of tree species will improve the habitat conditions gradually and thus the valuable germplasm of the important taxa will be conserved.
