Specimens of Chamaebatia foliolosa Benth. with nodule structures on their roots fix atmospheric nitrogen. The nodules are similar to those of other non‐legumes in gross morphology and structure, containing hyphal strands, some with club‐shaped vesicles at their ends. A fixation rate of 130 nmoles N 2 per g fresh weight per hr is reported by using 15 N 2 as a tracer. Equivalent rates of acetylene reduction were observed.
