Description
Color: Uniform dark tan with pale branch tips

Colonies are arborescent, sturdy, erect, tapering with large, tapered, prostrate branches. Axial corallites are bigger dome-shaped with small openings. Radial corallites occur only on the upper surfaces of branches; lower surfaces are smooth. They are of mixed sizes, the smallest are immersed, the largest are bead-like, up to 4 mm diameter. The coenosteum is smooth and dense, composed of fine spinules without elaborated tips. The radial corallites are observed only on the upper surface of the branches and lower surfaces are smooth and are of mixed sizes. The larger corallites are bead-like. Mostly the smaller corallites are round and immersed. The coenosteum is composed of flattened spines.

Similar species: This species is similar to Acropora hemprichii, which have smaller branches with corallites on all sides. The very large corallite size and rounded appearance of radial corallites, as well as the sturdy branches are distinctive features to identify this species in the field.
