The orientation leaflets are arranged in one or two pinnae pairs in a bipinnate compound. Each pinna also contains 10 to 26 leaflets. These plants grow on soil with little nutrient concentration and are not shade-tolerant. Similar to other Fabaceae plant species, the orientation of the leaves undergoes nyctinasty motions, sometimes known as "sleep," throughout the night and reopens in the light.
