Characters: Colonies are corymbose plates up to approximately one metre across, with short, uniform, evenly spaced, tapered branchlets up to 10 millimetres thick at the base. Axial corallites are tubular and conspicuous. Incipient axial corallites are common. Radial corallites are irregular, mostly tubular and appressed, with sharp edged nariform openings.
Colour: Usually a distinctive pale pinkish-brown, but is occasionally other colours. Pale grey tentacles are often extended during the day.
Similar Species: Acropora massawensis, which forms prostrate colonies and has less tubular radial corallites. See also A. lamarcki, which has less exsert and less tubular radial corallites.
Habitat: Upper reef slopes.
Abundance: Usually uncommon.
