%X Legume-Rhizobium symbiosis contribute substantially to nitrogen economy of the soil with global utilization in sustainable agricultural systems. Due to the immense importance of legumes, nodulation was studied in 66 Papilionoid species from Sacramento Valley in California. Majority of the species were abundantly nodulated under natural soil conditions or when grown in uninoculated garden soil indicating distribution of wide range of naturalized rhizobia. Nodulation in 12 species within 6 genera is reported for the first time. The general account presented here is essentially first step in quantifying the contribution of these nodulated species to the nitrogen cycle of the biosphere.
