Characters: Colonies are horizontal plates consisting of flattened branches which usually diverge fan-wise but which may form an irregular tangle. Branches usually have a central ridge which may be broad. There is little fusion of branches. Axial, incipient axial and radial corallites are distinct and numerous. Radial corallites occur laterally on old branches, but otherwise are scattered over branch surfaces.
Colour: Cream with white or blue branch ends.
Similar Species: Acropora pichoni, which has fewer corallites and less elongate branches which become highly fused and thus more plate-like.
Habitat: Lower reef slopes below 40 metres.
Abundance: May be locally common.
