Observed among roadside vegetation near Nairobi National Park, Kenya. December 2015.

This plant has been promoted for use in agroforestry restorations because the nitrogen fixing ability helps improve soil fertility. However, dense stands may be vulnerable to outbreaks of herbaceous insects such as the leaf beetle Mesoplatys. Follow the thumb link below for more on this associated insect.
