"Marine Invertebrates and Plants of the Living Reef," Dr. Patrick L. Colin. The branching and form of this species make it the most distinctive of the western Atlantic black corals. Colonies can be sizable, reaching over 1.5 m in both height and width, but are branched in nearly a single plane. The stems and branches bear fine, simple pinnately branched extensions known as pinnules.
