Characters: Colonies may be up to one metre across and consist of prostrate or irregular branches. Larger colonies have distinct orders of branches and sub-branches. Branches do not fuse. Axial corallites are distinct on all orders of sub-branches. Radial corallites are scattered over the whole branch surface and are appressed and tubular.
Similar Species: Acropora pichoni and A. tenella, both of which have much larger corallites and do not have distinctive orders of unfused branches.
