The habitat of this plant is sandy places among rocks by the coast. The stem is strong and stout, furrowed, with a few short, stiff hairs at first. The prickles are crowded, long, straight, and slender. The leaflets are large, dark-green above, felted below. The panicle is pyramidal, large, the partial rachis and long flower-stalks covered with fine acicles or needle-like points. The petals are large, roundish, milky-white. The contrasting colours, crowded long prickles, large panicle and white handsome flowers help to distinguish this species, and it is nearest to R. incurvatus and R. rhamnifolius.
