Characters: Colonies are hemispherical to flat. Valleys are sinuous or straight, averaging 35 millimetres wide and are usually separated by a narrow groove. Walls have a thick fleshy appearance. Septa are thick and have large teeth. Columellae are usually in two rows.
Colour: Brown, green or red, usually with distinctly contrasting valley and wall colours.
Habitat: Exposed upper reef slopes.
Taxonomic Note: Readily separated from other Symphyllia in situ. Collected specimens often do not have the diagnostic two rows of columellae centres.
