I don't think that a plant has to be a member of Leguminaceae to fix
nitrogen.  Kentucky coffeetree, once a member of the Leguminaceae, subfamily
Caesalpinoideae, now a seperate family Caesalpinaceae, fixes nitrogen. And,
perhaps more noticible are some of the Alders, members of the Betulaceae,
that fix nitrogen.

Perhaps a true plant taxonomist can come to my rescue. What is the most
recent classification of Robinia psuedoacacia, Gymnocladus dioicus and
Gleditsia triacanthos?
