Characters: Colonies have widely spaced, tapered upright branches with short side branches projecting almost perpendicularly. Axial corallites are dome-shaped and prominent. Incipient axial corallites occur irregularly and are long and tapered. These intergrade with radial corallites which are also widely spaced and tapered. All corallite openings are small and have weakly developed septa. The coenosteum is fine, giving branches a smooth appearance.
Colour: Reddish-brown.
Similar Species: Acropora vaughani, which has compact branches and less widely spaced and less conical radial corallites. See also A. tortuosa.
Habitat: Shallow reef environments.
Abundance: Uncommon.
Taxonomic Note: Placed in synonymy with Acropora variolosa by Wallace, Done and Muir (2012). It is distinguished by having upright branches and widely spaced corallites, differences readily seen in the Red Sea where these species occur together.
