Abstract

The leguminous annual Chamaecrista nictitans was often associated with the invasive C4 grass Pennisetum setaceum in Hawaiian grasslands. A greenhouse study demonstrated that P. setaceum seedlings planted under Heteropogon contortus canopies grew 60x faster on a biomass basis at high nitrogen levels than at low nitrogen levels, eventually exceeding the biomass of H. contortus. Chamaecrista nictitans did not directly facilitate P. setaceum growth, thus it is believed that the elevation of soil nitrogen associated with C. nictitans annual die-offs facilitates establishment of the invasive P. setaceum.
