Characters: Colonies are branching with compact, horizontally spread sub-branches occurring towards the extremities of main branches. Axial corallites are elongate. Radial corallites are tubular and irregular in length.
Colour: Tan or pale brown with white branch tips.
Similar species: Colonies may resemble small A. palmata in having closely compacted (elkhorn-like) sub-branches towards the ends of main branches. Main branches and corallites are similar to those of A. cervicornis.
Habitat: Very shallow reef slopes and lagoon margins.
