Veron and Wallace, 1984

Colonies are corymbose plates up to approximately one metre across, with short, uniform, evenly spaced, non-tapered branchlets bearing numerous elongate thin walled corallites. There is usually more than one axial corallite per branchlet. Radial corallites near branchlet tips are tubular and appressed.

Colour: Grey, cream, blue (which may photograph pink) or brown.

Habitat: A wide range of environments from lower reef slopes to lagoons.

Abundance: Common in Western Australia, rarely common elsewhere.

Similar species: Acropora desalwii , Acropora parapharaonis

Taxonomic note: Taxonomic note: Corals from the western Indian Ocean are attributed to this species with doubt. Source reference: Veron (2000). Taxonomic references: Veron and Wallace (1984), Wallace (1999). Additional identification guides: Veron (1986), Nishihira and Veron (1995).
