A large population of Azorhizobium caulinodans was present on Sesbania rostrata; up to 5 x 10 cm were found on leaves and fewer were found on flowers. Although A. caulinodans was also present on the leaves of Sesbania aculeata (nonhost), the populations were much smaller than that observed on S. rostrata. The population of S. aculeata rhizobia on host leaves was less than 30 cm, and their presence on host flowers was sporadic. Aeschynomene afraspera and Aeschynomene aspera rhizobia, which are profusely stem nodulating, were found on the leaves of host and nonhost plants and on the flowers of host plants, but, Aeschynomene pratensis and Aeschynomene sensitiva rhizobia were not found on the leaves and flowers of host plants.
在田菁上存在大量的根瘤菌属 Azorhizobium caulinodans；在叶片上最多可达 5 x 10 cm，而在花朵上则较少。虽然根瘤菌属 Azorhizobium caulinodans 也存在于猪屎豆（非宿主）的叶片上，但数量远小于在田菁上观察到的数量。宿主叶片上的猪屎豆根瘤菌的数量少于 30 cm，而其在宿主花朵上的存在则是零星的。在宿主和非宿主植物的叶片以及宿主植物的花朵上都发现了大量结瘤的含羞草根瘤菌属 Aeschynomene afraspera 和 Aeschynomene aspera，但在宿主植物的叶片和花朵上都没有发现含羞草属 Aeschynomene pratensis 和 Aeschynomene sensitiva 根瘤菌。
