Characters: Colonies are corymbose plates with crowded branchlets. Branchlets at the colony perimeter are mostly horizontal and distinct from those from the rest of the colony. Branchlets may have more than one axial corallite. Axial corallites and incipient axial corallites are long, tubular and upright, except towards plate margins where they are similar to radial corallites.
Colour: Pale brown, blue (which may photograph pink) or green, usually with distinct colouration of the colony margins.
Similar Species: Acropora parapharaonis, which has appressed, rounded radial corallites. See also A. willisae, which has fewer axial corallites and much shorter radial corallites and A. plana, which does not have distinctive branch development at plate margins.
Habitat: Shallow protected reefs.
