Characters: Colonies are dome-shaped clumps of interlocking branches up to 2 metres across. Branches are formed of single tubular corallites (or axial corallites) with lateral buds. Corallites are 5-8 millimetres diameter. Costal spines are widely spaced and not exsert. There is little tendency to form laminae or solid bases.
Colour: Pinkish-brown with pale corallite ends.
Habitat: Most shallow reef environments.
