Characters: Colonies are clumps of irregular fine upright or prostrate branches. These consist of little more than elongate axial corallites with widely spaced radial corallites. The undersurface of prostrate branches are usually devoid of corallites. Radial corallites are variable in size, but are mostly pocket-like, short and appressed, with nariform openings.
Colour: Pale brown branches with darker radial corallites and sometimes coloured axial corallites.
Similar Species: Acropora cardenae, which has finer, prostrate branches and alternating radial corallites primarily on the sides of branches.
Habitat: Associated with Halimeda banks at over 20 metres depth.
Abundance: Usually rare.
