Description: This plant is erect, 4-6 cm. high, dark pink 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 cgracilis2compressed and about 1 mm. broad. The axes are clothed with narrower short lateral branchlets that shorten to the apex. Branching pattern gives the plant a clumpy appearance.

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