Colonies are arborescent, with cylindrical branches. They usually form thickets and may form single species stands over 10 metres across. In shallow water branches are short and compact, while in deeper water colonies have more open branches. Axial corallites are exsert. Radial corallites are tubular. They may be similar or varied in size, and uniformly or irregularly distributed.
Usually cream, brown or blue, generally with pale branch ends.
Reef slopes and lagoons.
Common and frequently a dominant species.
