Characters: Colonies are usually upright compact bushes, but may form thick plates. Branches are short and sub-branches are frequent. Axial and incipient axial corallites are large and dome-shaped, with thick walls. They may become long and tubular. Radial corallites are small and inconspicuous. All corallites are smooth and rounded. The coenosteum is smooth.
Colour: Usually uniform blue (which may photograph pink) or cream.
Similar species: Acropora loripes, which has more exsert (pocket-like) radial corallites and is not uniformly coloured. See also A. rosaria and A. squarrosa.
