Colonies sprawl over the substrate and have dead bases so that they fall apart if disturbed. This is the smallest Anacropora, with most branches less than 3 millimetres thick. They are always contorted and tapered. Sometimes they are irregularly fused. Sub-branches form by equal division. Corallites are conical and project up to 1.5 millimetres from the branch surface. Corallites seldom form spines.
Cream or pale blue.
May cover extensive areas on lower reef slopes, especially in turbid water.
