Description: This plant is erect, 4-10 cm. high, deep purple in colour, arising from an encrusting basal layer attached securely to the substrate. The erect portion is a branched system of jointed segments. The segments below are cylindrical, about 0.75 mm. diameter; above slightly compressed and about 1mm. broad.  The axes are clothed with narrower short lateral branchlets, all approximately the same length. Branching in the lower region is distichously pinnate with branches usually simple; above distichously pinnateor verticillate with branchlets usually pinnately subdivided.

Habitat: On rocks in the lower intertidal and upper subtidal zones and in tide-pools.
