Characters: Colonies are thickets of spire-like branches. Branches are twisted and tapered and form sub-branches at obtuse angles. Corallite centres occur primarily where branches divide. All corallite structures are fine. Colour: Pale brown. Similar species: Pectinia teres and P. elongata, both of which have similar growth-forms where colonies consist primarily of spires, but both have much larger skeletal structures. From a distance may be mistaken for finely branched Seriatopora (Pocilloporidae). Habitat: Lower reef slopes, especially in turbid water. Abundance: Locally common.
