Characters: Colonies form thickets of intertwining bottlebrush branches, usually with only the distal 200 millimetres being alive. Branches divide irregularly and at frequent intervals to give a bushy colony shape. Axial and incipient axial corallites are tubular and tapered. Radial corallites are short and appressed.
Similar Species: Acropora echinata and A. carduus. Usually found with A. echinata, which has much longer axial corallites.
