Characters: Colonies are arborescent, composed of twisted branches which subdivide infrequently. They may form extensive compact stands. Axial corallites are small. Radial corallites are small and immersed, with circular outward facing openings. The coenosteum is coarse.
Similar Species: Acropora muricata, which has larger, more exsert radial and axial corallites. See also A. abrolhosensis, which has more exsert axial corallites.
Habitat: Shallow reef slopes and lagoons.
Taxonomic Note: Considered as 'unresolved' by Wallace (1999). However, this species is readily separated from its most similar congener, Acropora muricata, by its immersed radial corallites.
