Axial corallites are long and tubular and incipient axial corallites are irregular. Radial corallites are immersed on main branches and are triangular in shape, with nariform openings. Colour: Pale brown. Similar species: Acropora batunai, which has more compact branches and better development of branchlets and associated radial corallites. Habitat: Shallow reef environments. Abundance: Rare.
