Characters: Colonies are usually 0.5-1 metre across and are corymbose plates with widely spaced, slightly tapering branchlets. Axial corallites are small. Radial corallites are immersed or nearly so, giving branchlets a smooth appearance.
Colour: Pale brown or cream.
Similar Species: Acropora microclados, which has tubular radial corallites and incipient axial corallites. May be mistaken for fish-grazed or diseased colonies of other corymbose species where axial corallites are mostly immersed.
Habitat: Occurs only on upper reef slopes where Acropora diversity is high.
Abundance: Rare.
