Characters: Colonies are clumps of irregular branches. Axial corallites intergrade in size with radial corallites. Radial corallites are large, crowded and barrel-shaped.
Colour: Pale brown or yellow.
Similar Species: Isopora brueggemanni, which has smaller, less crowded radial corallites. See also Acropora chesterfieldensis.
Habitat: Upper reef slopes and lagoons.
Abundance: May be locally common, otherwise rare.
Taxonomic Note: Considered a junior synonym of Acropora digitifera by Wallace (1999) and Wallace, Done and Muir (2012). Growth forms are similar but A. schmitti has distinctive barrel-shaped radial corallites. Acropora schmitti has also been confused with small colonies of A. rudis which also has large corallites with small calices.
