  • a Letters in parentheses represent the subfamily to which the legume belongs (M, Mimosoideae; P, Papilionoideae), and the numbers represent the tribe (201). D = determinate nodules; I, indeterminate nodules.

  • b Data from reference 166. The data were taken from the reports of Wilson (279), who tested the nodulation capacity of 32 rhizobial isolates (from 31 legume genera) on the nodulation capacities of 160 species (78 genera), and Meyer z. A. and Broughton (see reference 157), who assayed the ability of 50 rhizobial isolates to nodulate 16 species (13 genera) of legumes.
