Colonies are semi-circular horizontal plates, usually less than one metre across. Plates are composed of regularly spaced horizontal branches with short inclined branchlets composed mostly of one or more axial and incipient axial corallites. Radial corallites are small and pocket-like.
Similar Species: Acropora caroliniana, which has larger, usually more tapered axial and incipient axial corallites.
