Usually solitary but sometimes two to four centres occur in one corallite, or occasionally in separate corallites. Corallites are saucer-shaped and less than 60 millimetres diameter. Septa are sturdy with blunt saw-like teeth.

Colour: Colourful, usually mixtures of cream, red, blue and green.

Habitat: Reef environments or on rocky headlands in high latitudes.

Abundance: Relatively common in subtropical localities, uncommon elsewhere.

Similar species: Scolymia cubensis
