Characters: Colonies are subarborescent with bottlebrush branches with upright main branches form clumps. Axial, incipient axial and radial corallites all intergrade. Axial corallites are long and tubular while the smallest radial corallites are pocket-like. All corallites have thick walls with round openings.
Colour: Uniform pale to dark brown.
Similar Species: Acropora longicyathus, which has shorter axial corallites and is therefore less bottlebrush-like. See also A. echinata, which has finer corallites.
Habitat: Shallow reef environments.
Abundance: Uncommon.
