Growing 3 to 4 meters tall with many five-angled, flexible branches that are initially silvery-silky hairy and become nearly hairless with age, it has a distinctive broom-like appearance. Its lower branches feature three-part leaflets less than 10 millimeters long that are lance-linear or oblong and covered in silvery-silky hairs, while upper branches are often nearly leafless. The plant produces linear-oblong fruits 2.5 to 3 centimeters long that are covered in appressed hairs.
