Colonies are small bushes, tending towards developing small tables. Branches are slender. Radial corallites range from being relatively long and slender, often arranged in neat rows, or may be strongly appressed. Axial corallites may be no larger than the radials, or noticeably larger, both features occurring on the same colonies. The corals are cream to brown. This is a very common coral, though it is small and not conspicuous. It is found in a wide range of habitats, but not in rough water (Sheppard, 1998). Colonies are irregularly corymbose with tapering branches up to 12 mm wide. Radial corallites are usually in neat rows and are nariform in shape. Colour: Cream or pale brown with blue branch tips, cream with brown corallites or greenish-brown with purple or blue corallites. Abundance: occurs in almost all Acropora assemblages but is especially common on upper reef slopes (Veron, 1986).
