Characters: Colonies have an encrusting or laminar base, with closely compacted short upright branches. Coenosteum ridges are mostly vertical but may be irregular. Corallites are large and prominent.
Colour: Dark brown, usually with white coenosteum ridges and branch tips.
Habitat: Shallow reef environments and rocky foreshores.
Abundance: Uncommon but distinctive.
Taxonomic Note: Morphological differences with Montipora confusa and M. undata, notably in form of coenosteum ridges, are most easily seen where these species co-occur.
