Characters: Colonies are small irregular clumps of branches, usually less than 0.3 metres across. Corallites are angular, with thick rounded walls. The ends of branches are ragged, being primarily composed of exsert costae. Septa are in two alternating orders and have large dentations. Columellae are small and compact. Paliform lobes form a distinct crown.
Colour: Uniform cream or brown.
Similar Species: This is the only branching Goniastrea. Corallites are similar to those of G. retiformis. Australogyra zelli has similar branch shapes but is much larger.
