The plants have branches that are characteristically composed of successive clavate segments, and divaricate dichotomously, trichotomously and sometimes alternately. The color of this species varies, and tends to be a yellowish brown in calm and sunny environments and is dark green to dark purple in places with water movement and low light. This seaweed is brittle, and grows on rocks in middle to lower intertidal zones along shorelines exposed to moderate to calm water movement.
