Characters: Colonies are flat plates, or tiers of plates with short digitate branchlets. Small colonies exposed to wave action have extensive encrusting bases and widely spaced branchlets. In most colonies branches are tightly compacted. Axial corallites are small. Radial corallites are tubular, uniform in size down branch sides and usually have slightly flaring lips.
Colour: Uniform green or brown.
Similar Species: Acropora digitifera, which has thinner branches which are not conical. Acropora monticulosa has larger branches and much larger radial corallites. See also A. seriata.
Habitat: Shallow rocky foreshores.
Abundance: Common in mainland Japan where it may be a dominant species.
Taxonomic Note: Delineation from high latitude Acropora digitifera remains unclear.
