Characters: Colonies are clumps of thin (up to 6 mm thick) branches. These are often irregularly fused. Corallites are mostly immersed, but have projecting lower lips which give the surface a rasp-like appearance underwater.
Colour: Brown or grey, sometimes with white tips.
Similar Species: Skeletal detail is similar to that of Montipora samarensis, but branches tend to have rougher surfaces and are more fused. See also M. digitata and M. porites.
Habitat: Shallow protected reef slopes.
Abundance: Common.
Taxonomic Note: May be difficult to separate from other branching Montipora.
