Its bright green cylindrical stems, densely covered in golden-yellow spines, grow prostrate or semi-erect on rocky coastal slopes with marine influence. The genus was established in honor of German naturalist Alwin Berger. Its only species, B. emoryi, is one of the few plants that grow on the rocky coastal cliffs of southern California.
