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 and radial corallites are distinct. Radial corallites only occur laterally on old branches, but otherwise are scattered over the branch surface.
Colour: Cream with white or blue branch ends.
Similar species: Acropora pichoni, which has less elongate branches which become highly fused and thus more plate-like.
