Characters: Colonies form corymbose or irregular cushions with thin elongate branches. Axial corallites are tubular in shape. Radial corallites are all the same size. They have prominent lower lips giving a scale-like appearance.
Colour: Dull creamy-brown, pink or blue (which may photograph purple), usually with distinctively coloured radial corallite lips.
Similar species: Acropora convexa, which has a more corymbose growth-form. See also A. millepora and A. pulchra, which have radial corallites of similar shape, but of mixed sizes.
