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.
Habitat: Upper reef slopes.
Taxonomic Note: Distinct species. Placed in synonymy with Acropora squarrosa by Wallace, Done and Muir (2012), apparently a nomenclatorial issue. These species, as illustrated here, are clearly distinct, see A. squarrosa for a summary of the issues involved.
