Characters: Colonies are encrusting to submassive with or without contorted nodular columns or branches. Corallites are immersed or exsert, cup-shaped, tubular, or ‘nariform’ (where openings on the sides of tuberculae give them the shape of a roman nose, as with corallites of nariform Acropora). Tuberculae may also be fused into smooth ridges.
Colour: Mottled or uniform purple or brown, usually with white polyps.
Similar Species: Plate-like colonies may resemble those of Montipora monasteriata. See also M. spongodes.
Habitat: Mostly upper reef slopes.
Abundance: Uncommon.
